Open Access The Leaching of Dolomitic

Agitation leaching is suitable for high grade ores (40-70 % solids) and increases percolation of acid into solids at differ-ent agitation speeds [1, 5]. Buffle plates, in addition to agita-tors, may be used to maximize slurry mixing [6]. Com-pressed air leaching in pachuca tanks is the most common method for leaching copper ore [7-9].

In the gold mining industry today, cyanide leaching is the prevailing method for solubilizing and recovering gold. Most of the new gold that is mined each year is processed via adsorption of gold cyanide onto activated carbon (Fleming et al. 2011). Typically, the carbon in pulp (CIP) or carbon in leach (CIL) process is used for gold recovery.

The study supported a conceptual flow sheet using the AmmLeach process in a heap leaching, solvent extraction and steam stripping process to produce a zinc oxide product. The adoption of heap leaching would also eliminate the need for milling, agitation leaching equipment and solid-liquid separation.

The paper presents laboratory report on leach study of a particular ZnS ore using a range of concentrated acid. The authors carried out this work as prelude to a more systematic study on the considerable body of knowledge in processing this type of ore in terms of the Roast-Leach-Electrowin process and then considered the extent to which this method is applicable to their specific ore.

The study demonstrated that the agitated leach route, followed by copper recovery using solvent extraction and electrowinning technology, is more economically viable than heap leaching for the life-of-mine, at the high copper oxide concentrations experienced in Copperbelt ores.

Understanding Leachate Analysis

• Sample leaching – the leaching matrix used, the mode of contact with the solid material, agitation method, etc • Preparation of the leachate – the type of separation used to obtain the eluate for analysis (centrifugation, decantation or filtration) and any sample preservation

Hydrometallurgy

Percolation leaching is conducted in a series of vats containing the crushed ore through which leaching solution is pumped to gradually put the metal into solution. Agitation leaching is used with very finely divided ores which may have already been partially processed and would pack too tightly for percolation methods.

The process design of gold leaching and carbon

Leaching reagents in the form of cyanide and an oxidant such as air or oxygen are added after thickening. Leaching takes place in a series of agitated leach reactors or pachucas. Before leaching the pH of the pulp is normally adjusted to a value of around 9.5–11 to ensure minimum loss of cyanide as hydrogen cyanide.
