Basics of Leaching Separation Technology Articles Hard Rock Mining Gold and Silver Ore and processing it

Simply put leaching generally refers to the removal of a substance from a solid via a liquid extraction media The desired component diffuses into the solvent from its natural solid form Examples of leaching include the removal of sugar from sugar beets with hot water and the removal of nickel salts or gold from their natural solid beds with sulfuric acid solutionsIn most gold ores the final process to extract the tiniest gold particles is the use of cyanide to dissolve the gold Cyanide in the presence of oxygen actually dissolves both gold and silver It is both efficient and inexpensive so it is widely used in precious metal ore processing

Applying Theory of Constraints to Manage BottlenecksMaterials processing Britannica

The theory of constraints is an important tool for improving process flows The implications of the theory are far reaching in terms of understanding bottlenecks to a process and better managing these bottlenecks to create an efficient process flowMaterials processing by hand is as old as civilization mechanization began with the Industrial Revolution of the 18th century and in the early 19th century the basic machines for forming shaping and cutting were developed principally in England Since then materials processing methods techniques and machinery have grown in variety and number
