Descriptions of the use of a flotation process have been found in ancient Greek and Persian literature suggesting its antiquity. During the late 19th century, the process basics were discovered through a slow evolutionary phase. During the first decade of the 20th century, a more rapid investigation of oils, froths, and agitation led to proven work-place applications, especially at Broken Hill, Australia, that brought the technological innovation known as “froth flotation.” During the early 20th century, it dramatically revoluti…read more
The ores from which silver and are recoverable by divide themselves naturally into two general processing classes: ores in which the valuable are those of the base metals, the precious metals being incidental constituents, and ores in which the and silver are of primary importance, the base-metal , if present, being of little or no value. The first class ...read more
