Gold Smelting & Refining Process - 911 Metallurgist

Feb 28, 2016· Gold concentrates, precipitates, and Merril-Crowe product can have mercury is variable proportion. If we smelt the charge directly at 1100 o C, mercury will be released to the environment and the smelting place can be a dangerous place. In order to avoid this situation, is necessary to eliminate mercury by retorting.

AMIT 145: Lesson 7 Leaching – Mining Mill Operator Training

Separation of gold-rich liquid from residual solids. Recovery of gold from pregnant solution. The gold is recovered from the loaded solution by precipitation with Zn dust in a process known as Merrill-Crowe. This process demands a clarified and de-aerated liquor. Today, modern practice utilizes Activated Carbon to strip the gold from solution.

3 Technologies in Exploration, Mining, and Processing

Mineral separation is dependent on both reagent chemistry and water chemistry (Fuerstenau et al., 1985). Flotation equipment (cells) provides the mechanism for air (as bubbles) to come into contact with mineral surfaces so chemical attachment can take place for separation of the selected mineral species.
