Handling acidic chemicals is a challenge in the chemical industry, requiring a careful choice of contact material. Certain thermoset organic coatings are applicable in low pH environments, but when particulate erosion is also present the performance demand is increased. This is the case in, e.g., stirred tanks for agitated leaching of copper ore, …

Typical cyanide concentrations used in practice range from 300 to 500 mg/l (0.03 to 0.05% as NaCN) depending on the mineralogy of the ore. The gold is recovered by means of either heap leaching or agitated pulp leaching. In heap or dump leaching the ore or agglomerated fine ore is stacked in heaps on a pad lined with an impermeable membrane.

Factors. Tank leaching is usually differentiated from vat leaching on the following factors: In tank leaching the material is ground sufficiently fine to form a slurry or pulp, which can flow under gravity or when pumped. In vat leaching typically a coarser material is placed in the vat for leaching, this reduces the cost of size reduction;

1. Introduction. Slurry tanks with working volumes in the range 500–5000 m 3 per tank are used in hydrometallurgical processes (e.g. leaching/digestion, precipitation, adsorption, oxidation, neutralization and storage) in the minerals industry. Multiple tanks operating with solid and liquid phases in continuous mode are commonly employed.

Impeller-agitated tanks. These can be operated as continuous leaching tanks, singly or in a series. If the solids feed is a mixture of particles of different settling velocities and if it is desirable that all particles reside in the leaching tank the same lengths of time, design of a continuous stirred leach tank is difficult and uncertain.

A cyanide leaching circuit usually consists of large agitated tanks for mixing mineral slurry with cyanide in order to extract gold. Typically, the slurry consists of 30-40% solids by weight with the solid particles being less than 100 microns (0.1mm) in size. Air or oxygen is often bubbled through the slurry to improve the leaching reaction.
