There are two main copper ore processing methods flotation and hydrometallurgical process In terms of process improvement the current research mainly focuses on the research of fast flotation early removal of waste reduction of overgrinding and unde

mineralisation which is being mined at the rate of about 1 million tons of ore per year Ore processing is by conventional cyanide heap leaching which produces a pregnant leach solution PLS containing 1–2 ppm of gold together with 1000 ppm or more of copper The PLS is treated by column ion exchange using Dow’s goldselective MINIX resin

There are mainly three types of copper ore sulfide type copper ore oxide type copper ore and mixed ore Based on abundant experiences on copper mining project Prominer supplies customized solution for different types of copper ore General processing technologies for copper ore are summarized as below I Physical processing technology Crushing Grinding Solution Flotation Process II Chemical processing technology Leaching 1 Flotation process

By using ore sorting equipment ore concentrates can be created at very low cost in small or remote mining installations The entire processing line can be planned in semimobile form and consists only of crushers screens belts and sorting machines This allows immense cost savings for transport since the waste rock is disposed of onsite
