Gold parting
Gold parting is the separating of gold from silver (and other metallic impurities). Gold and silver are often extracted from the same ores and are chemically similar and therefore difficult to separate. The alloy of gold and silver is called electrum. Generally speaking, the beneficiation methods of polymetallic gold ore include gravity separation, flotation, cyanidation and amalgamation,etc. Gravity Gold Extraction Methods From Three Types of Ore

How to Separate Coal from Coal Gangue in Middling Coal
Overview. Middling coal is an intermediate product between clean coal and coal gangue separated from raw coal by a jig in a coal washing plant. It is a mixture of clean coal and coal gangue. Middling coal has low calorific value, high ash content, easy to slag, and its price is much lower than that of clean coal.Separate the gold from unwanted rocks and minerals using one of several methods. You can mix the gold ore with sodium cyanide, which will attach itself to the gold and separate other elements such as zinc. Or pan the gold manually in water to separate gold from the gravel and sand in a stream. Refine the gold you have extracted and How to Extract, Separate & Refine Gold Sciencing

Recovery of Gold as By-Product from the Base-Metals Industries
Zn leach residues. 1. Introduction. Although most of the gold produced each year originates from primary gold ores or concentrates, a significant amount of gold is recovered as byproduct from the production of base metals (BMs) and from the recycling of scrap. From a gold world production of approximately 2600 metric tons in 2004, about INSTRUCTIONS: Work in groups of three.
