We are usually limited by practicality, finances and permitting to a simple crushing and grinding circuit, with a gravity recovery system for the free milling values and value-containing sulfides. Mt. Baker Mining and Metals is focused on providing a cost-effective and durable ore processing plant that includes a jaw crusher, hammer mill, size classification equipment, and sluice/shaker table.

Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore.Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.. The extraction of minerals from ore can be done two ways: placer mining, which uses water

Mill tailings are the coarsely and finely ground waste portions of mined material remaining after beneficiation operations have removed the valuable constituents from the ore. Characteristics The physical and chemical characteristics of tailings vary according to the ore being mined and the particular beneficiation operations used.

Dilution occurs when waste is unintentionally with material containing ore and sent to the mill. When a cost is given for Dilution, it is the cost of processing the waste material through the mill. Misclassification occurs when material containing grade (ore) is sent to an incorrect downstream location (i.e. a stockpile); for example, sending high grade material to a low grade stockpile.

01-01-2015· For the ore type evaluated, the application of HPGR and stirred mill technology is indicated to reduce energy consumption by up to 25% compared to conventional flowsheets with wet tumbling mills. The reduction of energy consumption and grinding media requirements of OPTION 4 offer a significant reduction in operating cost (OPEX), which has favorable effect on net present value (NPV).
