Analysis of Agitation Leaching Data — Methods and ...

agitation leach systems should enable better scale-up protocols to be developed. Acid consumption in copper heap leaching operations has been found to be a first-order chemical controlled system. The analysis of the data is relatively straightforward. However, the interpretation and scale-up is not as direct as for the agitation leaching system.

Bottle Roll Testing for Cyanidation of Gold Ores: Problems ...

Cyanide leaching of gold is a very common methodology for evaluation of low grade gold ores. Despite risks associated with cyanide, the method proved to be highly effective provided that necessary precautions are taken. Gold cyanidation in field scale is mainly conducted through heap leaching and tank leaching methods.

Heap leach modeling — A review of approaches to metal ...

Heap leaching is responsible for approximately 21 percent — 3.9 million metric tonnes — of copper production and 9 percent — 270 metric tonnes or 8.7 million ounces — of gold production worldwide. Given metal price assumptions of $2.25/lb for copper and $1,250/oz for gold, these portions of global production generate revenues of $19 billion and $11 billion, respectively.

Hydrometallurgy - AMML

Leach column sizes range from 100-500 mm diameter and up to 5 m tall. A small scale test in a 100 mm × 2 m column nominally requires 20 kg or ore. Tests usually include size by size assays on the feed ore and leach residues to allow calculation of metal recoveries over the different sizes of crushed rock.

Analysis of Agitation Leaching Data — Methods and ...

However the interpretation and scale-up is not as direct as for agitation leaching. The differences in the residence time distributions (RTDs) are required to properly account for the scale-up between test columns and field. The leaching of oxide copper in agitated systems has …
