Cyanide leaching. After the crushing and grinding stage of the CIL gold mine process, the slurry is added to 9 high efficiency cyanide leaching tanks arranged in steps. The first 2 gold ore slurry is cyanided first, and the last 6 7 leaching tanks Activated carbon is added while cyanidation is performed for countercurrent adsorption operation.
The CIL process The carbon in leach process, illustrated in Figure 3 is a variation of the CIP process. In this process carbon is added directly to the leach circuit so that the leaching and adsorption processes proceed simultaneously. Capital cost is reduced, as only one set of agitators for both leaching
Carbon leaching process is characterized by simultaneous gold leaching and adsorption stages, with normal leaching segments of 6 10 segments. In the leaching process, ensure the fineness of grinding products 200 mesh accounted for 85 95%, the pulp concentration accounts for 40 45%, then add a certain volume of CNFREE ECO gold leaching agent.
The Main features of the CIL system: 1. CIL tanks. The leach circuit comprises eight stainless steel tanks in series, located outdoors. Each tank is equipped with an agitator. The ﬁrst tank is a pure leach tank and the following seven are CIL tanks. The ﬂotation tailings slurry
CIL gold processing plant mainly consists of following steps: 1 The ore is first reduced in size to ensure that all non refractory gold is readily accessible for cyanide leaching, There are several variations of comminution circuits used in the gold leaching industry, such as: Multi stage crushing, then ball milling circuits, typical of ball mill and hyrocyclones.
