Ore

Metal ores are generally oxides, sulfides, silicates, or native metals (such as native copper) that are not commonly concentrated in the Earth's crust, or noble metals (not usually forming compounds) such as gold. The ores must be processed to extract the elements of interest from the waste rock and from the ore …

Processes of Ore Formation

Processes of Ore Formation. Current theories of the genesis of ore deposit can be divided into internal (endogene) and external (exogene) or surface processes. It must be understood that more than one mechanism may be responsible for the formation of an ore body.

PRODUCT GUIDE

We’ve already seen a few hints that iron ore might be looking a little similar in structure to the evolving oil markets of the late 1970’s/early 1980’s. The hot metal spread is similar in concept to oil ‘crack spreads’ in the sense that they represent a pricing and processing differential between a raw and a finished product.

How silver is made

Silver is rarely found alone, but mostly in ores which also contain lead, copper, gold, and other metals which may be commercially valuable. Silver emerges as a byproduct of processing these metals. To recover silver from zinc-bearing ores, the Parkes process is used. In this method, the ore is heated until it becomes molten.
