| titleOfInvention | A hydrometallurgical process using resin-in-neutralized-solution of a heap leaching effluent |
| abstract | The present invention refers to a hydro-metallurgical process using resin-in-neutralized-solution in heap leaching effluent. More specifically, the process is applicable to lateritic ore, nickel oxidate, cobalt oxidate or a mixture containing metals of interest - nickel, cobalt and other secondary metals, wherein ore is leached by adding an acid or a base with possible pH adjustment, aided by acid or base with neutralization of heap leaching effluent, by adding lime, limestone, soda or ammonia in the temperature of 70° to 95°C range, at pH in the pH4 to pH5 range; wherein soluble impurity species can be reduced or cementing/complexation techniques, comprising a neutralized leaching effluent, as slurry, made up of solid particles (precipitated compounds) and solution, but ore-free; which is fed into the RINS (resin-in-neutralized-solution) circuit, with no need for solid-liquid separation; wherein the resin-in-neutralized-solution circuit comprises multiple sequential vats stirred in countercurrent flow and wherein the loaded resin is separated from the slurry by screening. |
