A year ago, Jameson got his hands on a porphyry copper ore from South America, and his recently completed test work shows encouraging results. "We can get 100 per cent recovery up to about 300 microns," he said. Now Jameson is looking for a mine site willing to trial a full-scale installation of about 50 to 100 tonnes per hour.
1. Introduction. Flotation is a widely used, cost-effective separation technique for wastewater treatment [1], mineral beneficiation [2], micro-oxygenation of wine [3], fermentation [4], ink removal [5], plastic recycling [6] etc. Flotation techniques are used for the various chemical, mineral and biological industries.In this technique, components …
More ores are treated using froth flotation cells than by any other single machines or process. Non-metallics as well as metallics now being commercially recovered include gold, silver, copper, lead, zinc, iron, manganese, nickel, cobalt, molybdenum, graphite, phosphate, fluorspar, barite, feldspar and coal. Recent flotation research …
In flotation, ground ore particles are suspended in water in the flotation cell and conditioned with various reagents (e.g., collector, frother, activator, depressant, ... As shown in Table 1, it has been reported that around 10–20% of copper in the ore is lost in the tailings. The copper grade in the tailings is 0.04–0.2%, which is very ...

The Bateman otation mechanism was developed in. S 1993 and is presently marketed by the Bateman Pro-cess Equipment Limited. The BQR series of Bateman cells have a round tank design with cell sizes varying. Figure 8 A schematic diagram of the Bateman flotation cell (courtesy of Bateman Process Equipment, South Africa).
Froth flotation is the most effective industrial method used to separate fine-grained minerals. The main problem of complex ore flotation is the negative effect of interactions among minerals in slurry, leading to variation in surface properties during separation. In this review, studies on the interactive effect among minerals on the …
4. Place the 500 gm ore sample in a 2-liter flotation cell. Mount the cell on the flotation machine and lower the agitator into place. 5. Fill the 2-liter flotation cell with tap water to a level 1 inch from the overflow lip of the cell. Turn the agitator on with the air valve closed and allow 30 seconds for the solids to fully wet. 6.

Sodium cyanide. Sodium cyanide is mainly used to depress sphalerite in the first or lead-flotation stage in separating lead from zinc minerals. Its action on pyrite is nearly as strong as on sphalerite, but it does not affect galena unless a large excess is added or the contact time is too long. The effect of sodium cyanide is often intensified ...
