In the Lake Superior district jigs and tables have, of course, been retained, and in a few concentrators which treat sulphide copper ores tables have been retained owing to unusual conditions at the plants or the smelters that treat the mill concentrates. The flotation process, which was responsible for the almost complete change in …
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% copper.
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 ores from which silver and gold are recoverable by flotation divide themselves naturally into two general processing classes: ores in which the valuable minerals are those of the base metals, the precious metals being incidental constituents, and ores in which the gold and silver are of primary importance, the base-metal …
For low-grade molybdenum-copper ore, while ensuring the grade and recovery rate of molybdenum concentrate, the comprehensive recovery of copper should also be considered.Sometimes it is more …
Typically, rougher molybdenite flotation and recovery from bulk copper/molybdenum concentrates involves the use of alkalisulfides, Nokes reagents, cyanides, oxidants, and/or thermal treatment to depress copper sulfide minerals. The bulk copper/molybdenum feed generally varies from 0.2% Mo to 1.0% Mo, and with …
The result is that window adaptive partial least squares method is the most accurate method, which can accurately predict the copper concentrate grade of the next measurement period in advance and can be used to guide operations. Keywords: modeling, estimation, copper concentrate grade, copper flotation process. 1.
Production of copper concentrate that can be used for extraction of copper. 4. Salient Technical Features including Competing Features. The process is based on froth flotation of copper bearing minerals from ore after milling. The concentrate is dewatered and used for extraction of metal by pyro-metallurgical route. 5. Level/Scale of Development
To recover copper and molybdenum from their porphyry sulfide ores, several process flowsheets are applied, and two of them are shown in Fig. 1.[23, 24] As illustrated in Fig. 1 (a), [23, 25] the two-stage flotation flowsheet is the most widely adopted.In the first stage, copper and molybdenum sulfide concentrates are recovered together.

The copper concentrator produces 1050 mt/day of bulk Cu-Mo concentrate averaging 27% Cu and 0.6% Mo. Molybdenum plant feed is thickened to 62% solids and stored in two 150 cubic meter tanks. Two identical flotation circuits are fed from a constant head tank through changeable orifice plates thus maintaining steady feed rates.
Among those methods, flotation procedure, a method for mineral separation, is widely applied in smelters because of its great processing capacity as well as relatively small investment cost for equipment and reagents . Most importantly, for the recovery of copper in the form of sulfide, the flotation usually possesses better effects.
