150tph iron ore crushing plant in south africa - jxsc mine

JXSC engineer designed the process flowchart of 150TPH iron ore crushing plant for South Africa customers. This stone crusher plant layout on the basis of the iron ore information that customers offered.

The information: 0-50mm materials of the raw ores are 39.42%. The density of the perlite ore is 3-4T/M3, and salt content is 15-25%, moisture content is12%. The maximum feedstock size of iron ore is 1000mm, and only a bit.

The requirements of South Africa customer: The throughput of iron ore crusher plant should reach 150TPH. And they need automatic incline vibrating feeder, semi-automation mobile jaw crusher. The particle size of the final crushing stone should be 0-50mm.

iron ores are the main raw material of steel production companies. The iron is picked out from iron ores which crushed, milled, magnetic separation, flotation, gravity separation. The iron is usually found in the form of magnetite (Fe3O4, 72.4% Fe), hematite (Fe2O3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH)n(H2O), 55% Fe) or siderite (FeCO3, 48.2% Fe).

MagnetITe Magnetite is an iron oxide ore consisting mainly of Fe3O4, and a composite of Fe2O3 and FeO. It is black-gray with a specific gravity of about 5.15. It contains 72.4% Fe. O27.6% and has magnetic properties. Magnetic separation can be used in Beneficiation, which is very convenient. But it is not easy to restore because its structure is close. It becomes hematite After a long time of weathering.

Hematite The main element of hematite is Fe2O3, kermesinus, the specific gravity of about 5.15, it contains 70%Fe. O30%, and is the main iron ore. There are many types on the basis of the different structure, as red hematite, specular hematite, micaceous hematite, red ocher, etc.

Limonite Limonite is an iron ore that contains ferric hydroxide. It is a general term for Goethite HFeO2 and Lepidocrocite Feo (OH). The chemical formula of its main composition has been written as mFe2O3. NH2O, which is Yellowish Brown and contains about 62% Fe, 27% O and 11% H2O with a specific gravity of about 3.6 ~ 4.0.

Siderite Siderite is a ferrous carbonate ore, mainly of FeCO3, greenish-gray, specific gravity of about 3.8. There is a lot of calcium salt and magnesium salt in Siderite. The carbonate will absorb a large amount of heat at a high temperature of about 800 ~ 900 C and give off carbon dioxide. Therefore, we usually roast it before adding into the blast furnace.

vaccine technology transfer center to open in south africa

vaccine technology transfer center to open in south africa

JOHANNESBURG (AP) The World Health Organization is in talks to create the first-ever technology transfer hub for coronavirus vaccines in South Africa, a move to boost supply to the continent that's desperately in need of COVID-19 shots, the head of the U.N. agency announced.

The new consortium will include drug makers Biovac and Afrigen Biologics and Vaccines, a network of universities and the Africa Centres for Disease Control and Prevention. They will develop training facilities for other vaccine makers to make shots that use a genetic code of the spike protein, known as mRNA vaccines.

We are now in discussions with several companies that have indicated interest in providing their mRNA technology, said WHO director-general Tedros Adhanom Ghebreysus at a virtual press briefing on Monday. That technology is used in the Pfizer-BioNTech and Moderna vaccines.

Africa will soon be able to take responsibility for the health of our people, as a result of the new WHO-backed technology transfer hub, South African President Cyril Ramaphosa said in the press briefing.

Poor countries in Africa and elsewhere are facing dire shortages of COVID-19 jabs despite some countries having the ability to produce vaccines, lamented Lara Dovifat, a campaign and advocacy adviser for Doctors Without Borders.

Numerous factories in Canada, Bangladesh, Denmark and elsewhere have previously called for companies to immediately share their technology, saying their idle production lines could be churning out millions of doses if they weren't hampered by intellectual property and other restrictions.

South Africa accounts for nearly 40% of Africas total recorded COVID-19 infections and is currently suffering a rapid surge, but vaccine rollout has been slow, marked by delayed deliveries among other factors.

South Africa currently does not manufacture any COVID-19 vaccines from scratch, but its Aspen Pharmacare assembles the Johnson & Johnson shot by blending large batches of the ingredients sent by J&J and then putting the product in vials and packaging them, a process known as fill and finish. Earlier this month the company had to discard 2 million doses because they had ingredients produced in the U.S. in a factory under suspect conditions.

The climb in new cases has been extraordinarily rapid and steep over the past few weeks, Ramaphosa said Monday in his weekly letter to the nation. The number of daily new cases jumped from below 800 in early April to more than 13,000 in the past week. In other words, it increased more than 15-fold from the last low point.

Gauteng province, the country's most populous with the cities of Johannesburg and Pretoria, is the worst-affected by the current surge with 60% of the new cases. All public and private hospitals are full, yet the numbers of new confirmed cases continue to rise, the province's deputy premier, David Makhura, said Monday.

WHO officials said that while their new vaccine transfer technology will hopefully increase future supplies, it won't address the immediate crisis, since it will take months for any new factories to start producing shots.

With dozens of countries desperately waiting for more doses after the COVAX initiative, a U.N.-backed plan to distribute vaccines to poor countries faltered in recent months, the WHO has been trying to persuade rich countries to donate vaccines once their most vulnerable populations are immunized.

FETHI BELAIDCoroners in Tunisiawhich is experiencing its fourth and worst wave of the COVID-19 pandemic have run out of space, meaning the dead are often left in crowded hospital rooms alongside still suffering patients for 24 hours. The morgues are full, the health ministry says. Even the dead, it seems, are suffering.We are in a catastrophic situation the boat is sinking, Tunisias health ministry spokesperson Nisaf Ben Alaya told reporters this week. The health system collapsed, we can

Vietnam has received the first shipment of 2 million doses of the Moderna coronavirus vaccine donated by the U.S. government, the American embassy in Hanoi said on Saturday, as the Southeast Asian country battles its worst outbreak. The shipment, delivered via the COVAX sharing facility, is part of the 80 million vaccine doses President Joe Biden committed from U.S. vaccine supplies to support global needs, the embassy said in an emailed statement. After successfully containing the coronavirus for much of the pandemic, Vietnam has since late April faced a more stubborn outbreak that has prompted calls for the government to accelerate inoculations.

In the latest sign of the uneven state of the coronavirus pandemic around the world, a slew of countries in the Asia-Pacific region are rushing to impose restrictions on movement to contain surging cases, a full year and a half into a pandemic that many had originally handled deftly.

Lindsey Wasson/ReutersThe highly transmissible Delta coronavirus variant tore through an Oklahoma gym facility earlier this year, infecting dozens of teenagers, landing one unvaccinated person in the ICU and providing a stark reminder that the fight against COVID-19 is far from over.Low COVID vaccination rates, the highly transmissible variant, and disturbingly lax social distancing rules in the facility combined to fuel the outbreak, according to a CDC report.The report not only underscores the

(Reuters) -Having escaped the worst when the coronavirus pandemic erupted last year, Southeast Asia is now suffering dramatic rises in deaths and cases, while vaccination shortfalls and highly contagious variants derail containment efforts. As countries like Britain, Germany and France prepare to remove most remaining restrictions after devastating outbreaks, governments in Southeast Asia are tightening measures, hoping targeted lockdowns will act as circuit-breakers in arresting record jumps in cases and deaths that started rising in May. Indonesia, the region's hardest hit and most populous country, recorded more than 38,000 cases on Friday for a second successive day, six times the number a month earlier, in a week when its daily death toll as much as doubled from the start of July.

(Bloomberg) -- The U.S. Centers for Disease Control and Prevention is giving schools more flexibility to decide how to safely keep kids in kindergarten through 12th-grade classrooms while guarding against the further spread of Covid-19. Infections are rising across most regions of the world as the delta variant spreads, the World Health Organizations chief scientist said. The reproduction rate in England has risen to the highest levels since October.South Africas council on the coronavirus wil

The coronavirus pathogen has continuously mutated during the pandemic, often becoming more virulent strains. Infectious disease experts maintain that the mutated strains circulating in the United States do not evade protection from vaccines available in the U.S., but they pose a danger to holdouts who have not received their shots.

Walensky added that cases of COVID-19 are surging in counties representing 9 million people, and that the U.S. is seeing outbreaks of COVID-19 at summer camps and other community events.Nearly all deaths and hospitalizations nationwide are among unvaccinated people, said Jeff Zients, who leads the White House's COVID-19 response team.He said the spread of the Delta variant is particularly dangerous to young people. Research suggests it may cause more severe disease among younger people than other variants of the coronavirus.The CDC earlier this week said that the Delta variant of COVID-19 has already become the dominant strain in the United States. The variant, which is highly contagious, has also become dominant in other countries around the world.The White House plans to concentrate federal assistance for vaccinating against and treating COVID-19 in states including Arkansas, Missouri, Nevada and Illinois, Zients said, adding that the Biden administration is also working to make COVID-19 vaccines available at doctors' offices around the country.

Pfizer Inc plans to ask U.S. regulators to authorise a booster dose of its COVID-19 vaccine within the next month, the drugmaker's top scientist said on Thursday, based on evidence of greater risk of re-infection six months after inoculation and the spread of the highly contagious Delta variant. Pfizer's own data from the United States showed an erosion of the vaccine's efficacy after six months against the variants circulating there in the spring.

Tunisia's health care system is collapsing due to the coronavirus, with intensive care departments full and doctors overburdened by a rapid outbreak of cases and deaths, the health ministry said on Thursday. Tunisia recorded near 10,000 new coronavirus cases and 134 deaths on Wednesday, a daily record since the start of the pandemic, as concerns grow that the country will not be able to control the pandemic. After successfully containing the virus in the first wave last year, Tunisia is grappling with a rise in infections.
