WebAn acid solution is often mixed with the ore during agglomeration to initial leaching while the material is being stacked. After stacking, the heap is irrigated at a rate around 6–10 l m − 2 h − 1 with an acidic solution called raffinate which is returned from downstream SX. WebThe process involves leaching the material with a weak acid solution. This solution, known as pregnant liquor, is recovered and then contacted with an organic solvent, referred to as the extractant, in the solvent extraction stage (SX). WebOct 8, 2024 · The two minerals can only be reliably distinguished through chemical analysis. Carbonate minerals like calcite or smithsonite react with acids to efforvesce (fizz) while dissolving and producing CO 2 (see equation (1) below).
