Jun 26, 2021The principal ore of zinc used for its extraction is Zinc blend ( Z n S). As Zinc blend is a sulphide ore, the process used for its concentration is the Froth Floatation Method. The concentrated ore is then roasted in excess air at 1200 K to obtain zinc oxide ( Z n O). It is then reduced to Z n by coke at a temperature of 1673 K.

Mar 21, 2021In the past, when primary, secondary and tertiary crushers fed material directly to large ball mills, the energy efficiency of the concentrator was determined for the most part by the ball mill operation, whereas now the energy efficiency of a plant often rests largely on the SAG mill operation. As a result, mines have shifted their emphasis in

In the 16th century stamps (dropping pestles) began to be used to pulverize ore. Machine pulverization began to develop in the second half of the 19th century. The principle of operation of the ball mill, the basic pulverizing device, was already known 150 years earlier; the prototype of the modern mill was invented in the 1870's.

We have analytically derived a mathematical model of energy-saving ore grinding by a ball mill with a three-phase motion of grinding bodies, invariant to a change in the length of rods during wear. The model can estimate the energy efficiency of grinding larger pieces of ore based on the resulting volume of crushed large-lump material.
