Crushing Circuit Process Control

For optimization of crushing and screening plant operation, there is one aim, viz, to control the quantity and rate of energy applied to the ore. This can only be achieved by designing and controlling the plant to cater for variations in the feed material as previously discussed. Plants are normally run in either one of two modes: Maximum ...

Roasting in Metallurgy

Ores containing much pyrites might be freed from most of their sulphur by pile roasting, and then subjected to fine crushing and a dead roast in a reverberatory furnace, but the extra cost of handling would probably exceed the saving due to the smaller consumption of fuel. This system has not been tried in chlorination mills on an extensive …
