Silver & Gold Cyanide Leaching of Copper Ore
Table of ContentsEffect of Copper on Leaching of Pure GoldCyanidation of a Copper-Bearing Gold Ore Much work has been done on the effect of copper in cyanide solutions on the leaching of gold. It is generally accepted that copper in cyanide solutions can form complex ions such as Cu(CN)2-, Cu(CN)3=, and Cu(CN)4=-, although Cu(CN)3= is considered the most probable of these.

For the same reason pure
Effect of Regrinding
To ensure adequate mineral liberation is achieved ahead of the dilution cleaner circuit, a regrind mill is installed on the combined copper rougher-scavenger concentrate stream. See below the mineralogically limiting grade recovery chart, summarizing the theoretical limits to metallurgy imposed by the mineralogical associations in the cleaner circuit streams: Regrinding of the copper rougher-scavenger concentrate from P80=83µm to 32µm in

Mass Balancing Extended to Machine Learning
The methodology MIDAS Tech International has been developing has migrated from mass balancing to information theory to machine learning. It appears these methods are the only ones available that allow unit processes to be modelled in detail; entirely from the data. This is ideal for a simulation system that can be used for both data-driven models and imposed models (i.e.
Gold & Copper Bioleaching
Bacterial Leaching of Copper Ores Several types of bacteria capable of living in an acid environment have been isolated from copper mine waters. The foremost of these are of the genus Thiobacillus (T.). Thiobacillus bacteria are acidophilic aerobic chemolithotrophs which grow most rapidly at a pH in the range of 2-3. T. ferrooxidans derive their energy by oxidizing ferrous iron,

Difference Between SEDEX and VMS Deposits: Prospecting & Exploration
What are the Differences Between SEDEX and VMS Deposits and how the VMS and SEDEX deposits fit into the overall scheme of things. You remember that nature concentrates the metals by a process of partially melting crustal rocks at depth, letting the metal rise through the crust and cool, dumping the valueless material such as feldspar and amphibole on the way and
Starter Guide to Gold Prospecting and Mining
While venturing into a gold mine is fun and exciting, it can also be intimidating and dangerous as all mines are underneath the earth’s surface in some shape or form. Working in a gold mine is no easy job as it will take extensive amounts of time and effort to find any pieces of gold. In order to break ground
Mineralogical Liberation in Mineral Processing
When looking at your concentrate samples under the microscope in a size by size base, and want to evaluate your liberation % you can use this table.
Circulating Load Calculation Formula
Here is a formula that allows you to calculate the circulating load ratio around a ball mill and hydrocylone as part of a grinding circuit. For example your ball mill is in closed circuit with a set of cyclones. The grinding mill receives crushed ore feed. The pulp densities around your cyclone are sampled and known over an 8-hour shift, allowing

Gold/Silver Leaching with Sodium Zinc Cyanide
Dissolution of Precious Metals in Sodium Zinc Cyanide: The dissolving effect of sodium zinc cyanide on precious metals has been the subject of much discussion. According to one researcher, pure K2Zn(CN)4 in the presence of oxygen dissolves gold with the formation of gold potassium cyanide and zinc oxide. Another researcher compared the dissolving effects of KCN and K2Zn(CN)4 on gold. He found
