Heap Leaching. In contrast to dump leaching, heap leaching refers to the application of chemicals to lowgrade ore that has been crushed and deposited on a specially designed pad. The pad is lined with synthetic or natural materials such as polyethylene or compacted clay. Copper heap leach operations are much smaller than copper dump leaches.

Jul 10, 2017· 1) Vat Leaching: Also known as "agitated tank" leaching, the lixiviant comes into contact with the metal material in large vats or tanks, which can be stirred, enhancing the reaction kinetics. The metal containing solid, such as concentrate, ore, residue, or slag, often undergoes size reduction via crushing and grinding prior to leaching.

Heap (Dump) Leaching Where gold occurs in a form that does not require much grinding to free it from other material, a process known as heap or dump leaching can be applied. This is done on crushed ore (dump leaching does not use ground ore, otherwise it is identical) and is generally most suitable for permeable ore types.

Jul 05, 2018· How agglomeration improves heap leaching. A few key ways in which agglomeration results in improved copper (or other metal) recovery in the leaching process are improved heap permeability, an early start to the leaching process, increased particle penetration and improved particle strength control. Greater heap permeability

Bioleaching Wikipedia

Bioleaching can involve numerous ferrous iron and sulfur oxidizing bacteria, including Acidithiobacillus ferrooxidans (formerly known as Thiobacillus ferrooxidans) and Acidithiobacillus thiooxidans (formerly known as Thiobacillus thiooxidans). As a general principle, Fe 3+ ions are used to oxidize the ore. This step is entirely independent of microbes.
