Centrifugal gold concentrator was patented in China. It is an efficient equipment for recovering free gold in all particle size ranges,specially for recovery of fine gold which is lost during the operation of the gravitational concentrators(sluice boxes and jigs). It can be used not only for placer gold mining, but also for recover the natural gold from hard rocks, to replace amalgamation, and recover gold from the tailings.

Descriptions Centrifugal gold concentrator is a relatively new type of gravity concentration apparatus. The machines utilise the principles of a centrifuge to enhance the gravitational force experienced by feed particles to effect separation based on particle density. The key components of the unit are a cone shaped "concentrate" bowl, rotated at high speed by an electric motor and a pressurized water jacket encompassing the bowl. Feed material,typically from a ball mill discharge or cyclone underflow bleed, is fed as a slurry toward the centre of the bowl from above.The feed slurry contacts the base plate of the vessel and due to its rotation, is thrust outward.The outer extremities of the concentrate bowl house a series of ribs and between each pair of ribs is a groove. During operation the lighter material flows upward over the grooves and heavy mineral particles (usually of economic value) become trapped within them. Pressurized water is injected through a series of tangential water inlets along the perimeter of each groove to maintain a fluidized bed of particles in which heavy mineral particles can be efficiently concentrated.

It can be used not only for placer gold mining, but also for recover the natural gold from hard rocks, to replace amalgamation, and recover gold from the tailings.

Application shows that the recovery can be as high as 99%, and the concentrating ratio is up to 1,000 times. In recovering the natural gold in lode ore with size -0.074mm, the gold is up to 98%, For 0.004mm in particle size, the gold recovery is 97%.

1 High concentrating ratio and high recovery; 2 Steady recovery performance; 3 Center discharge design for fast,secure concentrate removal; 4 Environmentally friendly(requires no chemical additives or reagents); 5 Low water and electricity requirements; 6 Low production costs, durable wear parts, minimal maintenance requirements; 7 Compact design requiring less space, easy merged into the existing mining processing; 8 Quick payback on investment, typically lass than half year.

Our company developed automatic discharging system, now our new concentrators can be fully automated for washing. No longer needed wash concentrates by manpower, only needed push start and stop buttion on the antomatic control system to complete all works. Because whole process is closed operation, it can avoid man-made concentrate loss. Besides, our concentrator adopt soft materials at shock-absorbing places, it can effectually decrease negative effects issued from the vibration, and increase of service life.

Gold Centrifugal Concentrator is an efficient gravity separation machine that is useful in the recovery of free gold in all ranges of particle size, especially useful for recovering fine gold which gets lost during the operation of gravitational concentrators. It is not only used for placer gold mining, but it can also be used for the recovery of natural gold from rocks that are hard, for replacing amalgamation and recovering of gold from the tailings.

Capacity: 0-100 T/H Processible Material: alluvial gold, rock gold after grinding Applications: Mineral processing, Coal, Chemical, Petroleum, Food, Pharmaceutical, Mineral processing, etc. Main parts of concentrator machine: belt drive, motor, shaft sleeve, feed pipe, liner, jacket, tailings chute, vibrating isolation device, machine frame, concentrate outlet, hollow shaft, etc. Working principle of centrifuge concentrator: by rotating high-speed centrifuge rotor to generate strong centrifugal force, speed up the settlement of particles in the liquid, thus separate the materials by the difference of settlement coefficient and buoyancy density. The rotate drum, a cylinder that rotates around its axis at high speed, driven by an electric motor. The added soliquoid is moving to rotate at the same speed as the drum, under the centrifugal force, the components are separated and discharged respectively. Generally, the higher the rotate speed, the better the gold separation effect.

Types of industry centrifugal machine: centrifugal filter, spiral discharge settling centrifuge, centrifugal concentrator. Brand: Knelson concentrator, falcon concentrator, JXSC manufacturer Gold Centrifugal Concentrator advantages: High recovery and a high concentrating ratio Recovery performance is steady Has a center discharge design that enables fast and secure concentrate removal Eco-friendly ( needs no reagents or chemical additives) Low electricity and low water requirements Low cost of production, low maintenance requirements with durable wear parts Has a compact design needing less space and can be easily merged into an existing mining processing Fast returns on investment, usually less than 6 months.

This small scale rock gold processing plant is suitable for 1-2 tph capacity.It will include a jaw crusher, a hammer mill, a ball mill and 1-2 sets of shaking tables. Except these machines, you can also add a 8-10 meters belt conveyor and make a hopper with grizzly bars. It will help you to feed the ores by the load vehicle. Contact Us to get more details of this processing plant.

1. The 1st step Crushing. The Raw rock minerals will be fed into the crushers to get the discharge size less then 25mm. Usually it will need 2 crushers, the primary crusher is for cutting down the big size of rocks, and the second crushers is for getting the size of -25mm.

2. The 2nd step Grinding. The grinding machine will be ball mill or wet pan mill. If you need to grind the minerals without waters, then you should choose ball mill. The ball mill has a grinding rotary drum, there are liners inside of the drum. Usually the liners are manganese steel liners, some times, the customers ask the liners can be corrosion resistant, so we will make ceramic liners and rubber liners. The discharge size from the ball mill will be around 200 mesh. It will make a good performance for the mineral particle separators by gravity separators or flotation machines.

3. The 3rd step Separating. The discharge from the grinding machines will be in the size of 0-2mm. Most gravity separators can do a good work for separating the concentrate from the ores. It includes the shaking tables, centrifugal concentrators, jigger machines and spiral chutes. Sometime, we do also choose the flotation machines to get the concentrate mud. It depends on the ores situations.

Due to the size,shape and specific gravity of alluvial gold, the most effecient method is using washing plant. It always includes a trommel screen, vibrating sluice boxes, a centrifugal concentrator and shaking tabls. If the alluvial gold with very sticky clay, then the trommel screen should be changed into a rotary scrubber with a trommel screen.

We have more than 25 years experience, and the machines are sold to all over the world. Our engineers can go to your local mining site for leading the processing plant installation and train your staffs.

The Gold Centrifugal Concentrator is a kind of gravity separation equipment, industrial centrifuge widely used in gold panning industry for placer gold mining, but also for hard rock mining of natural gold, and also for recovery of gold from tailing. It is usually used in combination with the vibrating chute, gold shaker table, gold wash plant and other gold extraction equipment to increase the recovery rate.

The main parts of gold concentrator includes feeding pipe, drain pan, main shaft, spring, motor, tailing discharge mouth, belt. high-speed pin create power centrifugal force, in the process of gravity separation, light material would be discharged, gold gathers. Nowadays, the centrifugal concentrator is widely used for the recovery of gold, tungsten, lead, manganese, iron, etc. Gold centrifugal concentrator was patented in China. As a homemade gold separator, It is popular at home and aboard. Gold centrifugal concentrator is useful in the gold recovery in all ranges of particle size. It is most especially useful for recovering fine gold which gets lost during the operation of gravity concentrators. The application has shown that the recovery of gold can be very high, as much as 99% and the concentration ratio is up to 1,000 times. In the recovery of natural gold in lode ore that has a particle size of -0.074mm, the gold recovered is about 98%, for recovery of gold in a particle size of 0.004mm, it is up to 97%.
