As one of leaders of gold ore crushing work index industry, SBM always seeks innovation & excellence.
A Bond Ball Mill Work Index may also be used in the simulation and optimisation of existing mill(s) and the associated grinding circuit(s). Sample Requirements: A minimum of 10 kg of material crushed to nominally minus 10 mm is preferred. JKTech would stage crush the sample to minus 3.35 mm, as required for the Bond Ball Mill Work Index test feed.

Oct 25, 2015· It all depends hugely on the type of ore. Is the gold in Sulfides? Is is free? what size is the gold? Is it encased in quartz or other minerals? Many commercial hard rock mines will do 80 or 100 mesh, but screen between steps, so the ore is not over crushed. Once you reach the desired size, you don't want to keep crushing.

Ore is stockpiled (1) at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added (2) to raise the pH of the ore. Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding (SAG) mill (4) along with water and steel balls.

A single piece of gold ore generally has very little actual gold content. Although a very rich ore may have some visible gold present, the vast majority do not actually have any visible gold present, and only crushing and processing of the ore will release the gold within to host material. For example, lets say that a mine was processing ore ...

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, 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.
