The process development for copper ore started in 2001. The demonstration plant of HBL-SX-EW was run during 2001–2003. The commercial plant was started-up with ore throughput of about 1000 t/d in 2004,and it was expanded gradually in the following few years. ... and is well proved by practice (Lee, J., et al. 2011; Sand et al., 2001 ...

In the crushing process of copper ore processing, the two-stage-closed-circuit crushing-single-stage ball milling process is more common in small copper ore concentrators whose production scale is below 500t/d. Three-stage crushing is currently the most crushing and grinding process used by large and medium-sized copper ore concentrators.

Over 30 magmatic Ni-Cu-Co sulfide deposits have been discovered in China (Fig. 1), two of which are the world-class Jinchuan deposit and the super-large Xiarihamu deposit, with nickel metal resources exceeding one million tonnes representing ∼80% of China's nickel and cobalt resources [21].China's earliest discovered magmatic Ni-Cu-Co mineralisation is the …
