Crushing, Grinding and Concentration of the Ore ...

01/04/2020  The process of extracting metals from their ores is called metallurgy.. The ores are generally contaminated with earthly or undesired materials (impurities). These are called gangue or matrix.. The process of metallurgy depends upon the nature of the ore and the impurities present in it.. S ome common steps involved in the metallurgical operations are : 1) Crushing and grinding of the ore

In the figure below, the range of expected throughput for different ore types are plotted for a fixed grinding circuit; each ore type can process between 80% and 120% of the design throughput. An alternate power model was used to estimate mill throughput using the same mill sizes. In this case, a greater variation in throughput was predicted for the samples using the alternate power model ...

SAG Power Index (SPI) Test SGS

It is a measure of the hardness of the ore from a SAG or AG milling perspective. The test is a batch test, run with 2 kg of ore in a standard 10 cm diameter by 30 cm long mill, and it measures the time (in minutes) required to grind a sample from 80% passing 12.5 mm to 80% passing 1.70 mm. The key to the scale-up applicability and widespread international success of the SPI test is that all ...
