Separation of Copper and Molybdenum from Bulk Cu–Mo Concentrate …

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 …

How to Process Copper Lead Zinc Ore with Gold and Silver by …

The lead and copper must be removed in bulk as a mixed concentrate and then the zinc floated as a separate concentrate because of marketing requirements. A further separation of the lead-copper into their respective products by flotation is often economically advantageous if the crude ore contains 0.8% copper (16 pounds per ton) or more.
