The resources of the deposit in accordance with the JORC classification are 26.7 Mt of copper, with the copper grade in the ore (in accordance with the JORC classification) being 1.0%. The deposit is located in the Kalarsky district of the Trans-Baikal Territory, 30 km from Novaya Chara station of the Baikal-Amur Mainline.
Copper Ore Grinding Circuit Feed control is essential to efficient grinding and helps reduce surges and fluctuations throughout the entire plant. The Ball Mill in closed circuit with a Spiral Classifier discharges the pulp at about 60% minus 200 mesh.

Copper can be extracted from its ore by: Underground: sinking a vertical shaft into the Earth to an appropriate depth and driving horizontal tunnels into the ore. Open pit: 90% of ore is mined by this method. Ores near the surface can be quarried after removal of the surface layers.
Within the mineral processing industry, a range of grinding conditions exists which include semiautogenous grinding (SAG), rod milling, and conventional ball milling.
The ore can be treated by a typical porphyry copper flotation circuit producing a copper/gold concentrate. The concentrate is clean and free of deleterious elements which would attract smelter penalties. The processing circuit includes primary crushing underground, secondary crushing, high pressure grinding rolls, ball milling, rougher-scavenger flotation for all elements(Cu, Au, Ag), followed byregrinding the concentrate and cleaning,firstly in conventional cellsandthen in columns. A
Copper Ore Processing Methods. The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore People also ask How is ore processing in a copper flotation plant? General Description of Ore Processing in a Conventional Copper Flotation P lant Figure 1 is a generalized diagram of a conventional copper flotation plant from the point where ore first enters the circuit to the production of concentrate and tailings.

The rod mill and two ball mills are approximately the same size for simplified maintenance. Porphyry copper ores, usually medium to medium hard, require grinding to about 65-mesh to economically liberate the copper minerals from the gangue.
The control of a milling operation is a problem in imponderables: from the moment that the ore drops into the mill scoop the process becomes continuous, and continuity ceases only when the products finally come to rest at the concentrate bins and on the tailing dams. Material in process often cannot be weighed without a disturbance of continuity; consequently, mill control must depend upon the sampling of material in flux. From these samples the essential information is derived by means of
Material with a copper grade over 0.40% is loaded onto rail cars and sent to the crushing circuit, where rotating crushers reduce the size of the rocks by approximately 85%, to less than one-half of an inch. The ore is then sent to the rod and ball mills, which grind it in a mix with water to the consistency of fine powder.
The process plant is designed to treat 55 million tonnes per annum of copper ore from Sentinel mine, with a separate 4 million tonnes per annum circuit designed to process nickel ore feed from the Enterprise project or additional copper ore feed from Sentinel.
