copper flotation ton
Flotation of oxidized copper ores Inspiration. Copper is recovered from an aqueous pulp of an ore containing both sulfide minerals and oxidized minerals by continuously monitoring the EMF of the pulp and adding a water-soluble sulfide to the pulp in an amount from 0.05 to 7 pounds of contained sulfur per ton of ore whenever and for so long as the pump EMF is above about -30 millivolts with ...
Effect of Pulp Density on Gold Flotation Recovery
There are a host of other factors that could be discussed relative to their impact on the effectiveness of free gold flotation. One of the most consistent trends experienced over the years in gold flotation has been the need for carrying out flotations on ground ore pulps having relatively high percent solids loadings by weight. The data of Figure 5 from South Africa illustrates this point ...

When the ore is roughed, the pulp concentration is 25 35, and the flotation fine particles and the ore with high mud content is 10 20. When the flotation density of the mineral, the material particles are larger, the use of thick pulp. When the flotation density is small, the mineral of fine grain and slime material is used thinner pulp.

Flotation Developments amp Best Practice International
Pulp height is an extremely important process measurement, used to ensure that liquid pulp is not allowed to overflow to the launders. If pulp overflows, the flotation cell ceases to function effectively, or if the pulp is too low little material will flow over the launder, which are both very costly to the process.
Seven Factors Influence the Effect of the Froth Flotation
When the particle size of ore particle size is less than 0.01mm, the flotation index will deteriorate significantly. It is suggested that suitable grinding fineness should be determined by ore dressing test and production practice data. 2. Flotation Pulp Density. Pulp concentration is one of the main factors affecting the flotation index.
5 Ways The Copper Industry Can Improve Economics And
Dec 15, 2020 Advances in equipment and reagents focus on pursuing flotation of more ore with grain sizes up to a millimetre scale and operating at considerably higher pulp density
Flotation ore dressing Britannica
Flotation is widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores. Many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation process. This article was most recently revised and updated by Chelsey Parrott-Sheffer, Research Editor.
Analysis of the Effects of Grind Size on Production of
Fig 1 Flotation Cell during flotation of the ore . According to 7, the essence of flotation processes is the concentration of the finely divided minerals on the basis of variations in their ability to keep themselves on a phase interface. 8 also affirm that it is a means of treating a pulp of
A Brief Review of Pulp and Froth Rheology in Mineral Flotation
In mineral flotation, rheological problems have limited the efficient upgrading of low-grade and complex ores. Since pulp and froth rheology are deemed to play different roles in influencing the separation performance, in this paper, a brief review on pulp and froth rheology in flotation is provided, with an objective of developing a basic understanding of rheology in flotation.
INTERPRETATION OF FLOTATION DATA FOR THE
separation. Following a review of the initial flotation testwork results alterations are made to grind size coarser or finer, reagent system and flotation times to further enhance mineral recovery. Should recovery problems persist then a detailed mineralogical examination is recommended.
