Introducing Clean and Efficient Mercury Free Gold Processing to South West Burkina Faso. Burkina Faso has an artisanal and small scale gold mining sector that directly employs over 430,000 people and indirectly supports six times as many people via the secondary economy created by the sector. The economic support provided by ASGM and the skills diversification that it provides agrarian workers and rural villages is a fundamentally important feature of the Burkina Faso economy and one ...
In most cases, gold processing with cyanide leaching, usually with carbon adsorption, is still the core technology and the critical thing is understanding the mineralogy in order to optimise flowsheet selection and cost drivers, and get the best out of the process. Metallurgy: the science of bashing, mashing and hashing!

Gyro Gold produces a highly efficient, low maintenance gold separating solution. We maximize gold ore processing by shortening the gap between expected yield and marketable gold, thus achieving profitability earlier in the season. Gyro Gold provides operational analysis and customer service that is second to none.
Gold is then leached from the carbon particles by a strong solution of sodium cyanide and sodium hydroxide, and it is recovered from solution by electrowinning directly onto steel wool or by the Merrill Crowe process. In the latter process, the gold bearing solution is deoxygenated and passed through a filter press, where the gold is displaced from solution by reduction with zinc metal powder.
The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold. The Miller process is rapid and simple, but it produces gold of only about 99.5 percent purity. The Wohlwill process increases purity to about 99.99 percent by electrolysis.
Small miners employ this process due to alluvial deposits contain free gold, the process is fast and efficient, the final product has a high gold grade and recoveries are between 80 to 95%, commercialization is fast and simple without brokers, the process is simple and is not necessary a big investment or very special technical knowledge, the mercury can be reused and its losses are minimized, the final product weight is small and can be transported easily from the process plant to the ...
These gold professionals are specifically in gold processing through various beneficiation technologies, for gold ore of different characteristics, such as flotation, cyanide leaching, gravity separation, etc., to achieve the processing plant of optimal and cost efficient process designs. Prominer has established strategic relationships with equipment suppliers and commercial laboratories, so that together with advanced technology we deliver the best in gold processing plants.
