sequential flotation circuit versus Cadia s simple copper gold flotation circuit. The common theme is that pyrite forms the principal floatable concentrate diluent. Hellyer ore contains finely disseminated chalcopyrite, sphalerite, galena and tetrahedrite. The flotation plant design was
The requirement for metallic iron to precipitate (cement) the soluble copper in the proposed LPF process is about 1.25:1 (Fe:Cu) ratio. The flotation step in the final phase of the LPF process is readily accomplished by floating the cement copper at a pH of 6.5 with conventional collectors (Z-200 and AP407/242) and froth (MIBC).

The optimization test for the mineral processing process on Au-Cu-Fe polymetallic ore with Cu of 0.12%, Au of 0.12 g/t, S of 2.60% and Fe of 45.52% was studied. There are some problems such as difficulty in copper-sulfur separation, high lime consumption and unsatisfactory separation indexes that exist in the originally designed process of …
Three-stage cleaner flotation released grades of 25% Cu and 5–10 g/t Au at recoveries of 87% and 70% respectively for the chalcopyrite-pyrite ore. The chalcocite ore produced higher copper grades in the range of 60% Cu with 5–10 g/t Au, with similar recoveries to those of the chalcopyrite–pyrite ore.

The objective of this testwork programme was to consider the potential for hydrometallurgical processing of Platreef flotation concentrate containing 1.5 g/t Pt, 2.5 g/t Pd and 0.5 g/t Au, 1.5% Ni and 1.2% Cu. Some twenty-two process flowsheet variants were evaluated in a testwork programme examining several conventional and …
Copper Process Flowsheet Example. 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.
Abstract Metallurgical testing is the most essential part of any mineral processing flowsheet development.Its objectives must therefore be clearly defined.These are discussed together with the importance of the choice of the samples required for the test program.flowsheet development in mineral ...
In the Grasberg-Ertsberg case the process employed produces merely Cu-Au concentrate by flotation, which is further processed in copper smelters. Actually …

One could observe that the design of the flowsheet was more suited for a Cu concentrator than for Cu–Ni sequential flotation circuit with all the recycle streams built into it. Failure by the 2 (Cu and Ni) circuits to meet the targeted recovery and concentrate grades then necessitated the need to evaluate the original flowsheet to identify ...
Galena is the most important Pb-containing sulfide mineral, which normally associates with chalcopyrite.
