Leaching is a process widely used in extractive metallurgy where ore is treated with chemicals to convert the valuable metals within into soluble salts while the impurity remains insoluble. These can then be washed out and processed to give the pure metal; the materials left over are commonly known as tailings.Compared to pyrometallurgy leaching is easier to perform, …

To understand the effect of 4 h acid leaching on ore mineralogy and chemistry, the feed and leached solid products obtained at different temperatures were characterized (Fig. 1, Fig. 2 and Table 2).The XRD patterns of the feed ore and the solid residues obtained at 70 and 95 °C showed that the mineralogy was mainly composed of serpentine, goethite and smectite …

Roasted uranium ores are leached of their uranium values by both acidic and alkaline aqueous solutions. For the successful operation of all leaching systems, uranium must either be initially present in the more stable hexavalent state or be oxidized to that state in the leaching process. Acid leaching is commonly performed by agitating an ore-leach mixture for 4 to as long as 48 …

As the temperature increased, the copper leaching rate was significantly increased. Under the conditions at temperature of 80°C, the initial acid concentration of 160 g·L-1, leaching time of 2 h ...

Length of contact and dilution during agitation vary considerably for different ores. For gold ores agitation periods vary from 16 to 48 hr., probably averaging 30 hr., and for silver ores nearly twice this period.

Anawati et al. have previously explored the recovery of scandium from laterite nickel ore by acid roasting–water leaching. Nevertheless, the acid ore–water mixtures need to be heated at 50 °C for 24 h to ensure sulfation. ... Leaching experiments were conducted with agitation at different leaching durations, liquid-to-solid ratios, and ...

The cyanide leaching process is the most important method ever developed for extracting gold from its ores. The early development of the process is attributed to a Scotchman, John Stewart Mac Arthur, in collaboration with the Forrest brothers. The method was introduced into South Africa in 1890. From there it spread to Australia, Mexico and the ...

The invention relates to an agitation leaching method for ore paste, which takes concentrated sulfuric acid as a leaching agent, wherein the concentrated sulfuric acid is added to initial pasty ore pulp of which the concentration is 45-85% obtained by grinding, the weight of the concentrated sulfuric acid is 2%-120% of that of the ore, the leaching temperature in a …

Agitated Leaching The agitated leaching method is limited to those ores, or to that portion of those ores, that because of particle size do not …

Agitation leaching-Applications Commonly applied to a wide range of ore types, agitation leaching has been in use for well over 200 years. Leaching is typically performed in steel tanks, and the solids are kept in suspension by air or mechanical agitation. Air agitation in carried out in conical-bottomed leach tanks (Browns or Pachuca tanks) was widely practiced in the early …
