  • The Metallurgy of Cyanide Gold Leaching – An Introduction

    · Nature of Gold: The surface of a gold particle will typically be dissolved at a rate of around 0205 µm of surface depth per hour in a cyanide leach For large gold particles and nuggets, this is too slow to be fully dissolved in a typical processing plant Much simpler and less expensive gravity methods are available to recover this goldCIL gold processing plant mainly consists of following steps: 1 The ore is first reduced in size (typically 90% passing 200mesh ) to ensure that all nonrefractory gold is readily accessible for cyanide leaching, There are several variations of comminution circuits used in the gold leaching industry, such as: Multistage crushing, then ball milling circuits, typical of ball mill and hyrocyclonesCIL gold processing plant CIL processing plant for sale· Gold ore Prominer maintains a team of senior gold processing engineers with expertise and global experience These gold professionals are specifically in gold processing through various beneficiation technologies, for gold ore of different characteristics, such as flotation, cyanide leaching, gravity separation, etc, to achieve the processing plant of optimal and costefficient process designsGold Processing,Extraction,Smelting Plant Design

    The processing plant alternates between treating ore from the Martha Mine open pit and from the Favona underground mine Ore processing consists of the following stages: crushing and grinding of the ore ; addition of process water (generally decanted from the tailings pond) to form a slurry; addition of lime to the ore, and cyanide solution to the slurry, to leach the gold and silver intoThe sodium cyanide(or some other leaching reagent) solution is added into the first tank, and gold starts to be leached, most CIL plant will add the activated carbon from the second tank to the last one Carbon segregation screen is set in every absorption tank's outlet to separate the carbon and slurry Slurry flow automatically from the first tank to the last one based on the heightCarbon In Pulp Cyanide Leaching Gold Ore Processing
