Crusher, J101, where 80% of the ore ... is then sent to the electrowinning cells and subsequently to the refining process. Unit 500 ... In the electrowinning cells the gold is deposited onto steel wool hodes. An article about an electrowinning process at the Masbate Gold Mine gives information on how to establish a basecase design 1.
The process works best when the ore is crushed to small pieces before roasting. Additives, such as common rock salt are often added to the mix before it is heated to enhance the reaction of the sulfides. Once the ores are fully roasted, and the sulfur is driven off, the extraction of the gold or silver from the ore is not especially difficult.
The gold is recovered from this solution by electrowinning, zinc precipitation or refining technology such as the Mintek Minataur process. The eluted carbon may still contain various organic 48 2 4 4Au NaCN O H O NaAu CN NaOH+++ → + 22 2 The process design of gold leaching and carboninpulp circuits
· 3 Silver Powder Refined; 1 Gold Powder Refined; 5x Iron Powder Refined may be smelted to create an iron ingot. Since crushing and processing iron ore in a centrifuge yields ten Iron Powder Refined, each chunk of Iron Ore will produce two ingots if fully processed and smelted.
· gold processing, preparation of the ore for use in various products.. For thousands of years the word gold has connoted something of beauty or value. These images are derived from two properties of gold, its colour and its chemical colour of gold is due to the electronic structure of the gold atom, which absorbs electromagnetic radiation with wavelengths less than 5600 .

The process is applicable directly to gold bearing sand, and to goldbearing rocks after crushing. The crushing is effected by stonecrushers, rollingmills, and stampmills. The washing is carried out either by subjecting the material to the prolonged action of flowing water, or by mechanical agitation with water in deep iron pans or " cradles." In California hydraulic jets are employed to ...
