Cost Effective Ore Milling

Small-scale hard rock miners do not have the luxury of a fully equipped industrial-grade mill with flotation and cyanide leaching to process their ore and recover values. We are usually limited by practicality, finances and permitting to a simple crushing and grinding circuit, with a gravity recovery system for the free milling values and value-containing sulfides.

Glossary of Mining Terms

Coal washing — The process of separating undesirable materials from coal based on differences in densities. Pyritic sulfur, or sulfur combined with iron, is heavier and sinks in water; coal is lighter and floats. Coke — A hard, dry carbon substance produced by heating coal to a very high temperature in the absence of air. Coke is used in the manufacture of iron and steel.

Ethanol Production

Traditionally, ethanol from corn has primarily been produced through dry- and wet-milling processes. The majority of U.S. ethanol production is from dry-grind technology. The traditional dry-grind process grinds the whole corn kernel and mixes it with water and enzymes. The mash is then cooked to liquefy the starch further.

ECONOMIC AND TECHNICAL ANALYSIS OF ETHANOL DRY

The dry mill process does not separate the endosperm, germ, or bran of the corn kernel prior to fermentation as in the wet mill process. In the dry mill process the entire kernel is ground, enzymatically treated, fermented, and sent to the distillation column prior to product and co-product recovery.
