We are using Cyanide, Leach Aid and caustic to control the pH running for 18-24 hrs. Samples are taken within every 2 hrs for assay. Then at the end we get pregnant solution that will send to electrowinning, here its where challenge started. Our main problem we're facing copper is more coated in our mesh hence gold recovered is less.
