Crushed ore feeds this bin continuously and the bin overflows to a small conveyor feeding a dead stockpile. In the event of a primary crusher failure, the crusher loader is used to reclaim the stockpile via the surge bin, which doubles as an emergency hopper. • For coarse ore, the next alternative is a coarse ore

「why is ore crushed before any chemical process is

Crusher . A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.

2021-2-15  The process starts with crushed ore. A ball mill receives the crushed ore and reduces its particle size to the consistency of sand. Next, the ground ore from the mill often travels as a high-solid slurry to a cyclone. The cyclone separates fine particles from heavier particles, which return to the ball mill for further grinding.

The next stage is smelting. The gold is heated in a furnace with silica, borax and soda ash which soaks up most of the impurities, forming a slag which rises to the top of the furnace while the heavier gold settles to the bottom. This gold is poured into the bars that are shipped from the mine to be refined.
