Sulfide Ore Concentrator - Gold, Silver, Copper, Lead, Zinc

Usually, a complete set of sulfide flotation process equipment mainly includes raw material hopper, chute feeder, jaw crusher, vibrating screen, belt conveyor, vibrating feeder, storage bin, ball mill, spiral classifier , mixing tank, flotation machine, mud pump, thickener, disc vacuum filter.

The sulfide ore concentrator is suitable for processing sulfide ore gold, copper, silver, zinc, lead, fluorite and other ores, and has a high recovery rate for sulfide minerals. According to the material situation, it can usually reach about 85-90%.

Fully sulfide rock gold and copper flotation process equipment, including four major systems:

Crushing system:

The chute feeder is to feed raw materials stably and evenly to the coarse jaw crusher, and can feed stones of 0-300mm. If the size and capacity are larger, a grid vibrating feeder can be used. The primary jaw crusher then breaks the large rocks into smaller sizes, approximately 0-80mm. The output is sent to a fine jaw crusher for further crushing to particles under 25 mm. But there are still some +25mm particles, so it is best to send them to the vibrating screen to screen out the 0-25mm de-ball mill grinding system. +25mm back to finely ground again. The feed particle size of the ball mill can be smaller, the smaller the better, and the grinding efficiency will be much higher. So sometimes, there will be 3-stage crushers in the crushing system to make smaller feed size (0-5mm or 0-8mm or 0-10mm) for the ball mill.

Grinding system:

The 0-25mm material enters the storage bin before entering the ball mill, so as long as there is enough 0-25mm material in the storage bin, the crushing system can work separately from the grinding system. Then the 0-25mm material is sent into the ball mill through the swing feeder or the electromagnetic vibrating feeder through the belt conveyor. The ball mill is used to grind the material into a fine powder, because the flotation process requires 200 mesh materials, it needs to be used in conjunction with the spiral classifier, and the output from the overflow port of the classifier reaches 200 mesh, and the coarse particles in the underflow will return to the ball mill for grinding , becomes a closed circuit. So from this grinding system you will get a 200 mesh slurry.

Flotation system:

The 200-mesh pulp is first sent into the stirring tank by the pulp pump to make the materials fully mixed, and then enters the flotation machine from the stirring tank. Different chemicals need to be added to the flotation machine to separate different minerals. The flotation process includes primary election, secondary Secondary selection, final selection, this is the process of increasing the grade of minerals to the maximum. If you need a higher level, you need to float more times. Each concentrate ore is obtained through a flotation system.

Concentrate Filtration System:

After the mineral concentrates are obtained from the flotation system, for copper, zinc, lead, fluorite and other high-grade minerals, they are concentrated by a concentrator to make the density higher, and then sent to a disc vacuum filter to filter water and obtain more Much dry concentrate. It can then be dried in the sun or dried in a tumble dryer to obtain a completely dry mineral concentrate.

This sulfide ore flotation processing plant is very effective in recovering sulfide minerals. At the same time, it is suitable for the flotation and beneficiation of silver sulfide, zinc, lead, fluorite ore, copper and gold ore. The concentrator has high efficiency and high recovery rate, and is especially effective for fine-grained ore. It can obtain high-quality concentrate and fully utilize mineral resources. The design of sulfide flotation process equipment can be customized according to rock mineral conditions, and the capacity can be provided with small, medium and large capacity according to requirements.
