Mineral processing art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock or gangue It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive primary operations are comminution and concentration but there are other important operations
Data Processing 31 Calculation of the Exponent n and the Wi For any test the data collected is the size d 80 μm of the feed x 1 and the product 2 and the specific energy x 12 e kWhton used to achieve this size reduction Initially the work index i kWhton is calculated from 5 as W suming n 05 As explained

The Bond work index is a parameter which represents a measure of an ore resistance to grinding Numerically the work index represents the energy kWhsht required to reduce the material of one short ton from a theoretically infinite feed size to size at which 80 percent of material passes through sieve with square aperture100
Feb 25 2019 · Geologists look at the minerals in rocks to determine how much heat and pressure and thus how much metamorphosis the rock has undergone Certain minerals called index minerals only appear in certain rocks at certain pressures Thus index minerals can tell geologists how much the rock has metamorphosed
Mar 18 2020 · Canada Nickel Company TSXV CNC has announced initial results from a mineralogical assessment of its Crawford nickelcobalt project located 40 km north of Timmins Ontario The first phase of mineral processing work at the deposit was used to determine the proportion of nickel contained within the nickel sulphide minerals pentlandite and heazlewoodite and the nickeliron allow mineral
The aim of mineral processing is to get the mineral from rock or Ore that has good economic value in the market Generally the ability of treating crude material from excavation into mineral
Mineral processing Mineral processing Concentration Concentration involves the separation of valuable minerals from the other raw materials received from the grinding mill In largescale operations this is accomplished by taking advantage of the different properties of the minerals to be separated These properties can be colour optical sorting density gravity separation magnetic
