SUMMARY. The flotation plant flowsheet simulation models provide an efficient way to assess existing circuit operation, further optimize its operating conditions and to evaluate different circuit reconfigurations. When planning a new flotation plant design, simulation models can be used to design the circuit configuration and cell sizing.
Mass balancing is a common practice in preprocessing metallurgical data, for example, prior to calculating the recoveries of beneficiation processes. Balance calculations can be carried out quickly and robustly with highend data processing tools. Furthermore, the plant simulations, performance benchmarking and bottlenecking can be set up ...
and commissioned in November 2008. During the initial stages of sulphide operation, high copper (Cu)low zinc (Zn) ore was fed to the plant. Marketable copper concentrate at 9195% recovery was produced utilizing a highpH bulk sulphide rougher flotation and 2 cleaning stages. Because of increased levels of Zn
Testwork necessary to define the design parameters for a flotation circuit generally includes: Grindability studies to establish grinding power requirements. Chemical and mineralogical analyses of test composites to establish ore grades, mineral associations and liberation characteristics. Reagent evaluations required for rougher and cleaner ...
The above flowsheet is designed for the treatment by flotation of copper as chalcopyrite with gold and silver values. The ore, ranging from 6065% silica, with pyrite, arsenopyrite, and calcite with 3 to 4% copper. This flowsheet, though simple, is adequate for tonnages of 100 to 500 tons or more per day, depending on the size of equipment ...
Flowsheet development. Flotation testing. 1. Introduction. The project requirements of laboratory flotation testing. This review discusses flotation testing at the 12 kg batch scale. The metallurgical engineer arranging the flotation test programme typically wants clear, unambiguous results showing "before" and "after" test ...
The future of flotation. Woodgrove Technologies' staged flotation reactor (SFR) divides the flotation process into three chambers. Courtesy of Woodgrove Technologies. A s design criteria go, removing the froth layer from froth flotation makes a bold statement. The fact that such a device not only exists, but has 50 operating installations ...
Comparison of a simplified linear (left) and a circular (right) hydrometallurgical flowsheet for batterygrade cobalt and nickel production. For the circular process, a conceptual flowsheet is shown, with the reintroduction of protons to the system via hydrogen gas or via SXassisted carbonation with CO acid is regenerated, and the basemetal impurities are removed as metal carbonates.
This report provides a perspective on the amount of water used by a conventional copper flotation plant, including the makeup water required to compensate for water losses. Much of the global supply of copper originates from mines that also produce byproduct molybdenum, but for simplicity, a single copper concentrate has been modeled for this ...
The underflow is sent to a secondary ball mill and trommel screen, for additional grinding and classification. Using froth flotation, the copper minerals separate from the gangue and rise to the froth layer of the flotation cell. In turn, the copperrich bubbles are removed or transferred to the next stage of flotation for further processing.

After grinding, the mill discharge flowed into an agitating tank, which was used for adding 40g/t of Z 200 reagent and intensive pulp mixing before flotation. For copper flotation, one rougher flotation machine, two scavengers with adding 10 g/t of Z 200 and three cleaners with 400 g/t of lime were adopted.
This molybdenum flotation circuit, based on 250500 tons per 24 hours is designed for lowgrade molybdenum ore having highgrade streaks and with pyritequartz is also basically sound for many other friable sulphide ores, such as antimony, silver and even some lead ores.
