A novel hydrometallurgical process for ndida copper concentrates has been developed by The Minerals Laboratory of BHP. The ndida Process consists of concentrate leaching, solution purification, electrowinning and residue flotation. Part of the copper will be sold as high grade concentrate and part as high purity SX-EW copper. Contrary to previous efforts …

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.

The ODX project base case is an open pit mining operation that will be larger than any existing open pit mine operation in Australia and will rival BHP Billiton's giant ndida copper mine in northern Chile. The Mine Development team will eventually top 100 employees and will make up about half of the total ODX project team.

Introduction to Coal Flotation Coal flotation is essential in processing coal fines, usually below 250 μm, sometimes up to 1 mm. With the rise of longwall mining methods, the production of fines has increased, making flotation more critical. Environmental regulations have driven the use of flotation as the primary method for recovering coal fines.
