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
The bond work index test obtained high work index 5260 kwht and consumed power 1172 kwht to grind one ton of low grade iron ore and this attributed to the high concentration and hardness of
Before you can calculate the potential mineral deposit value you first need to gather some specific data regarding the ore body and the individual drill results This required data can be found in the mining companys press releases in which they announce their drill resultsMake sure that this data is announced according to the guidelines of National Instrument 43101 ie approved by a
Mineral Formulae Recalculation ExerciseThis problem set uses the above spreadsheets to recalculate mineral formulae assign cation site occupancy determine relative proportions of end members introduces important varieties of the rock forming minerals and requires students to look critically at the data and assumptions that are built into

In the case of multiple processing options cutoff grade is used to determine which process or destination the ore will be sent to by using the following equation Where U1 is the utility of sending ore to process 1 and U2 is the utility of sending ore to process 2 Utility is defined as the value economic or otherwise of selecting a process
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 metallurgyThe primary operations are comminution and concentration but there are other important operations
100AIM The aim of this experiment is to determine the Bond Work Index of a quartz sample using the laboratory ball mill 200INTRODUCTION The Bond Work Index was developed by Fred C Bond and was first published in 1961 The index relates to the energy required in kwht to reduce a given material from theoretically infinite feed size to 80 passing 100 microns 1
Mineral processing refers to the process of separating valuable minerals from their ores The simplest and most tedious method of separating ores from gangue involves picking out the individual elements More modern methods of mineral processing involve separation using the difference in mineral
Our dedicated team of geologists and engineers bring decades of international mining industry experience spanning the full mining cycle from project generation and exploration through mining mineral processing and reclamation
