Apr 14, conditioning and bulk flotation the classifier overflow at 90% minus 200 mesh and approximately 20% solids with a ph of about 10 is conditioned with dow reagent z-200. this reagent has both promoting and frothing characteristics favorable to flotation of the copper and zinc with a minimum of.
Apr 14, copper recovery was between 70-75% on this difficult ore. by lowering the copper grade and increasing recovery the zinc content would become excessive. the smelter did not permit copper with over 10% zn. flotation machines “sub-a” flotation cells of the cell to cell type are recommended for all the flotation steps in this treatment.
Aug 28, the copper and lead separation from bulk concentrate is usually carried out in two ways: depression of copper and lead flotation (cyanide method), and the copper flotation and depression of lead . according to the obtained results from about 40 industrial units which enriche the sulfide base metals complexes, it is concluded that firstly, in.

In this paper, the flotation behaviour of nickel-copper ores processed in the sudbury area is discusse~ with emphasis on the effect of oxidation on individual minerals, pnmarily pyrrholite. in general, moderate oxidation of a freshly ground ore promotes the flotability of all principal sulphides in the ore leading to a bulk flotation.
Jan 01, base metals such as copper, lead, and zinc are mainly extracted from sulfide ores. mostly these base metals tend to exist together in an ore. flotation process is widely used to separate these minerals in sulfide ores . a wide range of chemical reagents are used in the flotation process to separate the different.
Jan 08, in these tests, a zinc flotation was also performed to measure the metallurgical performance of that metal. the flowsheet schematic and summary of test results. as shown in the summary tables, copper was, on average, 63% recovered into the copper concentrate grading 24%.

Jun 15, the bureau of mines investigated the flotation responses of two copper nickel ore samples from the duluth complex with the objective of recovering bulk sulfide concentrates. one of the ores studied was taken from a test pit; the other was taken from a test shaft. the samples were quite similar except that the pit sample analyzed 0.35 pct cu and 0.11 pct ni and the shaft sample analyzed.
Low zinc (zn) ore was fed to the plant. marketable copper concentrate at 91-95% recovery was produced utilizing a high-ph bulk sulphide rougher flotation and 2 cleaning stages. because of increased levels of zn of the ore body, a cu/zn separation circuit was initiated in early following an intensive laboratory test work.
Mar 23, copper ore flotation process copper ore flotation is generally a … bornite ore dressing plants mostly use the grinding and separation processes of … more detailed. bulk flotation of complex copper ore from … the undergraduate thesis attach hereto entitled “bulk flotation of complex copper ore.

The complexity of the ore leads to certain ways of treating it by the use of sequential flotation in which copper and zinc are floated in series of operation that may involve a bulk flotation of copper and zinc feeding it to another circuit of copper and zinc separation in order to produce both marketable value of copper and zinc concentrate (bulatovic,.
The flotation of complex sulfide copper ores. complex ore are often characterized by particularly fine intergrowth of the mineral values. due to this specific mineralogical characteristic, it is necessary to finely grind and concentrate ore prior to the solubilization of valuable metals (makita, et.al..
The presence of shale, the source of carbonaceous matter in the ore, has also a negative effect on flotation and pyrometallurgical processes. the presence of clay minerals and organic carbon in shale makes the production of high quality flotation concentrates, without excessive loss of copper and other metals in the flotation tailing,.
