Timed Flotation Test Cumulative Grade Recovery Curve As flotation response of the ore and shape of the recovery time curve is an unknown Depending on the ore the shape and position of the recovery time can vary considerably It is only when we have a fourth data point that the curve The minerological analysis of sample showed that sphalerite galena chalcopyrite and their oxidised forms are the main ore minerals in the sample while pyrite illite quartz calcite and gypsum are the gangue minerals The metal contents of the sample are 1 2% Zn 0 75% Pb and 0 06% Cu Flotation tests to produce bulk concentrate of copper-lead and lead-zinc were unsatisfactory The

Electrostatic concentration of phosphate flotation

Flotation concentrate with a head grade of about 28 5% was used for the triboelectrostatic separation experiments A representative sample from the flotation concentrate was prepared for triboelectrostatic separation The samples were vacuum dried between 80 and 100 C before being fed through a vibratory feeder into the separator

For preliminary work a composite sample was made from 21 lots taken from different parts of the mine and concentrate produced by treating the finely crushed ore in a 10-lb flotation machine The sample taken for this test assayed originally 1 54 oz gold and 0 28 oz silver

Upgrade of SLon Concentrate with the use of Froth Flotation on a typical African Iron Ore M Krugera S was an as received flotation feed sample which was screened at 38 micron The +38 micron material was then milled for 25 minutes and submitted for MLA analysis For the MLA investigation the aim was to determine the bulk mineralogy hematite and gangue mineral liberation

Veterinary Advice Online - Fecal Flotation A fecal flotation test otherwise known as a 'fecal float' egg flotation or Fecalyzer Test (Fecalyzer also spelled Fecalyser being the most commonly used in-house commercial product) is a diagnostic test commonly performed in-house in most veterinary clinics as a way of diagnosing parasitism in animals

Filtration Of Concentrate After Flotation The results indicated that the improvement in gold extraction after filtration and oxidation of the original pulp was due to partial removal of the flotation reagents and illustrates the detrimental effects that residual flotation reagents can have on the extraction of gold by cyanidation of a flotation concentration

A separate sample of the high grade table tailings was subjected to flotation at starvation reagent levels 45 3% of the residual silver was recovered at a grade of 13 450 g/t (393 4 oz/t) which is equivalent to a combined gravity and flotation silver recovery of 67 2% The resultant concentrate analysis will give an indication of overall recovery Concentrate test work is ongoing The
