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 …
All the flotation test-work was done using the Denver laboratory machine with a 1.5l stainless steel flotation cell. The required mass of nickel-copper sulphide ore material ground to 70% passing 75 µm was weighed and placed in the flotation cell. This was followed by the addition of distilled water to about

Copper grade in concentrate (E), copper grade in tailings (- ), and copper recov- ery in a concentrate (H) were selected as factors for the evaluation of the flotation per- formance (performance indicators).
The flotation method is a technique widely used for the recovery of gold from gold-containing copper ores, base metal ores, copper nickel ores, platinum group ores and …
The valuable minerals of a copper sulfide ore in Chile, mainly consist of chalcopyrite and chalcocite as well as contain small amounts of cuprite.
This study is focused on the froth flotation reprocessing of a copper mineral from flotation tailings. The effects of flotation parameters including pulp density, collector dosage, frother dosage ...
However, one of the most interesting methods is froth flotation. Froth flotation works by exploiting the hydrophobic properties of gold molecules. First, ore is ground into an extremely fine powder. The powdered ore is mixed with water to create a slurry, which is mixed with surfactants to increase the gold's hydrophobicity.
Six flotation tests were conducted using the copper–gold ore and its mixtures with quartz, clay minerals and gypsum. Fig. 1 shows the mass recovery as a function of water recovery from these tests. As can be seen, flotation of the ore or baseline resulted in a 5% mass recovery and 31% water recovery at the completion of flotation.
Using Laboratory bench-top float test results and their retention (flotation) time to scale-up to real life full scale plant time can be done using the following tables and examples.
Due to the diversity of the geological aspects between the copper ore deposit, which implies different structures between the chemical and physical conditions of these, in addition to various configurations that make up the flotation cells between concentrate plants, it is interesting to replicate this study in other mining plants, in order …
