grinding media were the result of increased corrosion between this media type and the sulphide minerals in the ore. It was postulated that the improvement in fine (–3 micron) galena flotation response when the ore was ground with high chrome grinding media was due to lower levels of oxidized iron species within that system.

(1) Crushing and Grinding of the Ore The ores occur in nature as huge lumps. They are broken to small pieces with the help of crushers or grinders. These pieces are then reduced to fine powder with the help of a ball mill or stamp mill. This process is called pulverisation. (2) Concentration of Ore or Ore Benefaction

Metallurgy is the process of extracting pure metal from its ore. Naturally, most of the metals are found in their combined state. So it becomes essential to extract the pure form of metal for various other domestic and commercial purposes. Minerals from which metals can be easily extracted are called Ores.

Ores. Ores are minerals from which metal can be extracted easily and profitably. Types of Ores. Ores are classified into four types: Oxides ores, carbonate ores, sulphide ores, and halides ores. 1. Crushing and Grinding of Ore. The majority of ores found in nature occur as large rocks. Crushers are used to break them down into small pieces.

The froth is skimmed off and the resulting lead sulphide concentrate is dried. During this process, the ore, which may contain only 5% lead, is upgraded to a concentrate with 50% or more lead. At Broken Hill, concentrate grades average about 70% lead, mainly because the relatively coarse grain of the ore allows excellent recovery of lead sulphides.
