Ore crushing
Iron ore beneficiation plant asset in Brazil (iron ore crushing, processing).Ore crushing is a key process to handle the run-of-mine ore minerals like iron ore, gold, bauxite, copper, manganese, nickel, coal etc. at ore dressing plant. Generally, three phase crushing process will be adopted to deal with ores: coarse crushing, medium crushing and fine crushing. The popular ore crushers are jaw crusher, hammer crusher, impact crusher, cone crusher and VSI crusher.
The ore crushing process goes as follows:
raw ore minerals ->jaw crusher -> impact crusher -> cone crusher (VSI crusher) -> final products in different grade.
Through the coarse crushing by jaw crusher, the size of ore is less than 1m in diameter, and after medium crushing, the crusher breaks down boulders into lumps about the size of a footballand fine crushing, the size will be reduced to less than 12mmwhich is ingrapefruit-sized lumps.
From there, it is sent to stockpiles. Waste rock from the mine, which is low in ore mineral content, is retained for use in rehabilitation. This forms a closed cycle.
Ore grinding
Ball grinding mill used in bauxite ore dressing plant for fineness grinding.Ore grinding process plays an important role in ore beneficiation plant. The ore milling machine grind the crushed ore minerals into fine even ultrafine powder so that the leaching and smelting process can go smoothly.
Ore grinding mills can be divided into wet grinding and dry grinding. According to the different application, there will be open-circuit grinding and closed-circuit grinding process. The most popular ore milling machine are SAG mill, ball mill, Raymond mill, vertical mill, trapezium mill.
Our engineer will design different grinding lines for the customers according to customers’ requirements and the nature of the minerals.
Ore dressing plant
Ore dressing plant is a major part of ore beneficiation plant.Usually, we will equip the ore dressing plant with jaw crusher, impactor, cone crusher, ball mill, trapezium mill, classifier, magnetic separator, flotation machines, thickener, dryers and other ancillary equipment like conveyors, vibrating feeders, screens, washers etc. The whole unit feature with high efficiency, low energy consumption, high capacity, economical and so on.
The flow chart is:
Big raw ore minerals are fed into the heavy duty jaw crusher evenly and gradually for primary crushing, After the coarse crushing, the crushed ores will be conveyed to impact crusher for medium crushing, finally, the crushed ore will be transferred to cone crusher (VSI crusher either) for fineness crushing. When the crushing process is finished, the ores will be separated by sieving equipment like multi-deck vibrating screen. Then, the crushed ores will be transported to grinding plant for ore grinding.
The ore grinding plant will grind the ore into powder less than 0.4mm, then classification process goes on. The spiral classifier can washed and classified the mixture ore. After classifying, ore particles are sent to flotation machines, depending on the mineral characteristics with different chemicals, making the needed ores and other materials to be separated.
At the beneficiation plant, the ores will be leaching and smelting in the smelting furnace.
According to the requirements of the capacity, we can design the different stone crushing plant
