A Bond rod mill work index test (BRMWI) is a standard test for determining the rod mill work index of an ore sample [21]. The BRMWI is a measure of the resistance of the material to crushing and grinding in a rod mill and is used to calculate the grinding power needed for a given material parcel regarding rod mill grinding conditions. Along with other Bond tests, BRMWI is used to design semi

Traditional measurements of ore grindability are the Bond Work Index (Wi) values (Bond, 1952), divided into a low energy crushing work index (Wi C) for coarse rocks (75-50 mm), a rod mill work index (Wi RM) for intermediate sized particles (25-3 mm), and a ball mill work index (Wi

Sizing a crusher can be done reliably calculated thanks to the Impact/Crushing Work Index and the testwork research done by Fred Chester Bond and his 1952 paper. According to Bond ’s Third Theory of Comminution , the work/energy input is proportional to the new crack tip length created during particle breakage and equivalent to the work represented by the product – the feed.

The first stage is to crush the rocks to smaller fine gravels that will allow for gold molecules to be extracted. The crushing of gold-bearing rocks is not as easy as it may seem. This is because the rocks have to be crushed to very fine gravels that can allow for gold molecules to be dissolved in mercury or any other chemical used to extract gold from the ore.

To crush the gold ore in order to obtain pure gold, the large ore of gold is fed into a jaw crusher or mobile jaw crusher for the primary crushing process. The crushing process acts as a medium of screening the fine gold ore. It is then sieved using the vibrating screen and later sent through the use of a conveyer belt.
