This work investigated the separation of copper (Cu) and molybdenum (Mo) from bulk Cu–Mo concentrate using pressurized water leaching (PWL) and Hallimond tube flotation. The effects of pressure, temperature, stirring speed, and solid–liquid ratio on the dissolution efficiency of copper and molybdenum were investigated using PWL. The results showed that …

A simplified schematic drawing of copper flotation flowsheet. Run-of-mine open pit ore will be crushed in a gyratory crusher. The crushed ore will be processed by means of semi-autogenous and ball mill grinding followed by rougher flotation, regrind, cleaner flotation, and dewatering to produce copper concentrate.
