Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.% ore and 25% steel. The ball mill is operated in closed circuit with a particlesize measurement device and sizecontrol cyclones.

Limonitic (oxide) lateric ores are usually treated by hydrometallurgical methods: the Caron Process and Pressure Acid Leaching (PAL), Figure 3. Ores with high levels of magnesium are treated by the Caron process: using selective reduction of the ore, and ammonia leaching. This method is more energy intensive, and produces lower metal recovery.

Sep 24, 2018 · In basic terms the cost of mining and milling remained the same but the value of each tonne of ore was less because of dilution. This resulted in .
Dilution is the waste material not separated from the ore in the stages of mining, and is sent to the processing plant. It is defined at the ratio of tonnage waste mined and sent for processing over the combined ore and waste tonnage milled. The following equation is the expression used for dilution:
In a mining plant or processing mill, they have a big grinding circuit for crushing raw material, these are usually Ball or SAG mills. Inside these Sag/Ball mill are big steel balls that grind ore via an impact process. In simple terms, these hard metal steel balls get to the top of the rotating chamber and fall down crushing the ore being ...
