Embracing Coarse Particle Flotation. To dig a little deeper into some of these "elegant and precise" technologies, E&MJ turned to Eric Wasmund, global managing director at Eriez Flotation. "With CPF, you don't have to grind the ore to the fine endpoint that's required for conventional flotation technology," he explained.

in terms of the separation of ore particles by flotation. The MFT results are thus analysed in terms of minerals rather than metals. A phenomenological approach is then applied to decouple the recovery by true flotation from that by entrainment based on the recovery of the gangue minerals (Savassi, in press). The kinetics of true flotation of each

The ore was subjected to high power density microwave treatments in a single mode cavity at 15 kW and approximately 2 kW h/t. The untreated and microwave-treated samples were subsequently milled to two grind sizes near the nominal plant grind size and a size-by-liberation analysis performed.

However, the ability to exploit microwave-induced fracture by improving flotation recovery and grade, and/or increasing the primary grind size to effect liberation has significant potential benefits in terms of increasing plant throughput and metal production while reducing metal specific energy consumption, even without significant reductions in ore competency.

Grinding is continuous and fully integrated with subsequent flotation operations. SAG or AG mills. The crushed products are ground in SAG or AG mills. The self-grinding machine can grind ore without grinding media such as iron ball, or steel rod, as long as the hardness of the ore is sufficient for the rolling ore to grind by itself.

In this case, the hypogene ore carried a range of copper sulphides including chalcopyrite (26.3%), bornite (50.9%), and chalcocite (17.1%), with minor covellite, occurring at a very small mean grain size of 7-27 μm. It would be uneconomical to grind the ore down to these sizes to deliver good liberation before flotation.

The negative effect of Ore B on flotation performance was clearly seen in the mixture. The copper recovery in Ore A was 71% under the base flotation conditions, and dropped to 22% when it was mixed with Ore B. Therefore, the flotation conditions were changed, and the optimum conditions developed for Ore B were applied to the blend ore.

In its early days flotation promised, not only the ability to treat slime, but also a great simplicity of flowsheets attributable to the fact that all that had to be done was to grind the ore to a fine pulp and then float it. Flotation was the powerful new tool to which all refractory ores would respond.
