simultaneously in order to provide a uniform blend of weight recovery and of product quality (constant silica content). The range of ore weight recovery is 20% to 40%. The concentrate silica content ranges from 27a to nearly 15X silica. These ores are blended to result in a composite analysis of about 6% +/- .2% silica and 30% weight recovery.

Bulk Density - an overview | ScienceDirect Topics

Dec 14, 2013· Direct reduced iron (DRI) is also known as sponge iron. It is produced by the reduction of iron ore (in the form of lumps or pellets) by either non-coking coal or a reducing gas produced by reforming of natural gas. The reducing gas can also be produced by the gasification of coal. The reducing gas is normally a mixture.

Recovery and dilution usually are interrelated; with some methods of stoping a high recovery involves contamination of the ore from the walls or capping, and often clean ore can be obtained only by leaving some ore in the mine. In open-stope mines the greatest loss of ore is that tied up in pillars left for support of the back or hanging wall. The amount of ore thus left varies considerably ...
