Gold ore processing •Zinc dust is then added to the cyanide solution to chemically reduce the gold to the metal. 2Au(CN) 2 + Zn 2Au+ Zn(CN) 4 •The metallic gold is then filtered out refined. Smelting of resultant powder (rich Au) into steel molds and the slug is remove from the top furnace. Electrolysis is done to get high gold grade %
Extractive Metallurgy. Extractive metallurgy is the practice of removing valuable metals from an ore and refining the extracted raw metals into a purer form. In order to convert a metal oxide or sulfide to a purer metal, the ore must be reduced physically, chemically, or electrolytically.
11/21/2008· But anode for this process is Bullion, and AgNO3 is the solution. Silver will be at cathode and gold at anode, then smelting process is done to get gold and silver bar. We must do the electrolysis to get 99,99%, the solution of gold electrolysis is Au(Cl)2. 2. High Au Bullion

anvil to work the metal. This is a result of gold''s properties of malleability and ductility. The earliest tools were stone, bone, wood, and sinew, all of which were more than adequate to work gold nuggets straight from the earth. 5 Basic Principles of Metallurgy and Metalworking
Extractive metallurgy is the branch of metallurgical engineering that is associated with the separation of valuable minerals or metals from specific resources such as runofmine ores and recyclable materials as well as their recovery into saleable raw material products.
Sustainable metallurgy Introduction Until a few centuries ago, mankind made use of only seven metals—copper, tin, iron, gold, silver, lead, and mercury— in pure form or in the form of alloys (, bronze) [1]. In the early nineteenth century, metallic zinc began to be produced, although this metal had been used for centuries as a component
