Modeling and optimization of Carbon in leach (CIL) circuit
2015年11月1日 CIL circuit is a process of continuous leaching of gold from ore to liquid and counter-current adsorption of gold from liquid to carbon particles in a series of tanks. The CIL process concentrates gold from 2.5–3.5 g/t in ore to 2000 to 6000 g/t on carbon.

Study on the improvement of the zinc pressure leaching
2020年8月1日 Abstract. The first two-stage zinc pressure leaching plant with 100 kt-Zn/a capacity in China was put into production in 2009, to recover zinc, rare metals, germanium and gallium. However, the total extraction of zinc is limited to just 93% in initial production. To improve the co-recovery of metals, pressure leaching tests were carried out on ...

Leaching is carried out by two main methods: simple leaching at ambient temperature and atmospheric pressure; and pressure leaching, in which pressure and temperature are increased in order to accelerate the operation. The method chosen depends on the grade of the feed material, with richer feed accommodating a costlier, more extensive treatment.
