2016-9-9 Crushing is performed in stages using a combination of jaw, cone and impact crushers and is performed dry. The material is moved by mechanical means with conveyor belts. Sometimes the blasting and crushing fines are washed off the ore, and pumped as a slurry directly to the grinding circuit.

More## Crushing Circuit - an overview ScienceDirect Topics

The first step of physical beneficiation is crushing and grinding the iron ore to its liberation size, the maximum size where individual particles of gangue are separated from the iron minerals. A flow sheet of a typical iron ore crushing and grinding circuit is shown in Figure 1.2.2 (based on Ref. [4]).This type of flow sheet is usually followed when the crude ore contains below 30% iron.

Grinding circuits are fed at a controlled rate from the stockpile or bins holding the crusher plant product. There may be a number of grinding circuits in parallel, each circuit taking a definite fraction of the feed. An example is the Highland Valley Cu/Mo plant with five parallel grinding lines (Chapter 12).
