gold. Much of the free gold that is not recovered in the gravity stage during grinding is recovered to the copper concentrate. More recently, Telfer has been processing ores from a secondary deposit, namely West Dome. Whereas, the Main Dome, Telfer's primary ore source, is generally well liberated following grinding to a nominal target P 80

The first step of physical beneficiation is crushing and grinding the iron ore to its liberation size, the maximum size where individual particles of gangue are separated from the iron minerals. A flow sheet of a typical iron ore crushing and grinding circuit is shown in Figure (based on Ref. [4]).This type of flow sheet is usually followed when the crude ore contains below 30% iron.

Hard rock gold deposits can be further classified into three sub classes: free milling, sulfide associated and refractory. FreeMilling Gold. Gold ore is considered freemilling when over 90% of the gold can be recovered by a conventional gravitycyanidation process with low reagent consumptions at a grind size of 80% passing 75 µm.

Crushing and Grinding. Single stage crushing for the average small mill (100 tons or less) is adequate. The crushed ore at approximately minus 1 inch is wet ground in a Ball Mill to free the gold and sulfide values. Grinding is in closed circuit with a classifier and in this case a 48 mesh grind was necessary.

This complete process plant is for recovering gold by gravity concentration and froth flotation. This commonly applies, but is not limited to, ore deposits containing GRG gold and sulphide minerals rich in gold (such as: Pyrite, Copper). This process will also recover silver associated with sulphide minerals. This simple metallurgical concentrator includes single stage crushing, conveying ...

Chapter 2 Ore Handling. Ore handling is a key function in mining and mineral processing, which may account for 3060% of the total delivered price of raw materials. It covers the processes of transportation, storage, feeding, and washing of the ore en route to, or during, the various stages of treatment in the mill.
