Clean Mining is working to transform gold production worldwide through new processing technology that eliminates cyanide as a means of extracting the precious yellow metal. The solution represents transformational change achieved through the commercialisation of new, environmentallyconscious ore processing that sets a new ''gold standard''.

Gold Mine Heap Leaching Process. Crushed by jaw crushers and cone crushers to a certain particle size (3050mm), raw ore is directly sent for heaping or granulated (to make finer particles agglomerate into coarse powder), and then transported to the ore heap site for heap construction.
Gold, silver, copper, lead, zinc, molybdenum, iron, potash, phosphate, and even sand for glass are often processed by froth flotation. Without froth flotation, many of the metals and minerals used every day in our modern world would be much more expensive. Solvent Extraction Solvent extraction is a hydrometallurgical process. The process entails:
Outlining best practices in gold processing from a variety of perspectives, Gold Ore Processing: Project Development and Operations is a musthave reference for anyone working in the gold industry, including metallurgists, geologists, chemists, mining engineers, and many others.
The industrial processing of ores containing precious metals such as gold is generally very mining site specific. The variety of various mineral processing techniques employed is extensive and includes size reduction, size classification, gravity separation, roasting, cyanidation, chemical and/or bacterial leaching, ion exchange and/or solvent extraction, and froth flotation.
easy to find reagents which can easily dissolve gold. The reagents which can dissolve the gold, like cyanide, chloride or sulfur complexes, are mostly aggressive and very toxic [2] [3]. Therefore, we face environmental problems during chemical processing. New leaching reagents and new leaching techniques have been searched
Silver processing, preparation of the ore for use in various products. Silver has long been valued for its white metallic lustre, its ability to be readily worked, and its resistance to the corrosive effects of moisture and oxygen. The lustre of the pure metal is due to its electron configuration,
Cyanide, mercuryfree gold process a reality FIRST gold has been produced using a nontoxic chemical process designed to provide an alternative to using cyanide and mercury to extract the yellow metal.
GOLD FLOTATION The flotation process, which is today so extensively used for the concentration of basemetal sulphide ores and is finding increased use in many other fields. In 1932 flotation plants began to be installed for the treatment of gold and silver ores as a .

Nov 21, 2008· Generally, extraction process of all metal always include the Comminution (Size Reduction)to liberate achieve mineral. The next process of gold extraction from Hydrometallurgy route is Leaching. There are reagents that can be used to gold leaching process: Mercury (Hg), Cyanide (CN) usual as KCN or NaCN, Thiosulphate (Na2S2O3), and Thiourea.
CLEAN Mining, a company involved in the development of the Going for Gold process technology that liberates gold without the use of cyanide or mercury, has taken full ownership of the technology. ... The company worked with national science agency CSIRO to develop the technology that uses nontoxic reagent thiosulphate.
About 2% of these are general reagents. A wide variety of gold separation reagent options are available to you, such as general reagents, specific reagents. There are 27 gold separation reagent suppliers, mainly located in Asia. The top supplying country or region is China, which supply of gold separation reagent respectively.

this mining operation. The process is currently unprofitable with a gold price around 300 per ounce. Process Description Unit 100 – Size Reduction of Ore The BFD of the overall process is shown in Figure 1. The PFD for Unit 100, shown in Figure 2, is designed to reduce tons/hr of gold ore from a feed range of 25" to 160 microns.
