US3596838A Flotation of sulphide ores Google Patents

Flotation of sulphide minerals from their ores is achieved by a process in which two or more conditioning steps are carried out prior to a froth flotation step. The first step comprises conditioning a pulp of the ore in the presence of at least one alkaline agent selected from a group of agents which is defined in the specification which follows.

Froth Flotation Process Detailed Explanation With

Sulphide ores can be easily wetted by the oils which will float on water. These minerals are first converted into a fine powder and then mixed with water. After that pine oil is poured into this slurry. Then Air bubbles are created by injecting high-pressure air. Thus the sulphide ore comes on the top with the froth and oil. The remaining gangue particles which did not dissolve in oil settle

Froth-flotation process is used to concentrate sulphide ores.

Froth floatation process is especially suitable for sulphide ores. It is based on the difference in wetting characters of the ore and gangue with water and oil. Thus, both Assertion and Reason are correct and Reason is the correct explanation for Assertion.

Sulphide Minerals Flotation Plant Xinhai

The froth flotation and concentration method used exclusively for sulphide ores varies according to the mineral composition and ore floatability. The mainly used design flow is compressed air-pine oil and flotation reagent-foam containing sulfide ore and outlet for gangue.

Froth flotation of Aljustrel sulphide complex ore

Abstract: Froth flotation of copper-zinc-lead ores is a complex process based on similar metallurgy processing and strong interactions between chalcopyrite and sphalerite. These types of ores represent 15% of the world production and 7.5% of copper deposits all over the world. In the present study, an attempt is made to assess the feasibility of froth flotation of a complex sulphide ore, where

metal sulphides (BMS). Froth flotation is used to beneficiate these PGE ores. The process constitutes a bulk sulphide recovery. Improvement of recovery of the BMS is required to maximise the recovery of PGEs. The performance of the froth flotation process is largely dependent on the chemical additives used and these chemicals have been extensively studied. Mixtures of collectors are widely

Principles and practice of sulphide mineral flotation

Simplified flow sheets of representative flotation plant operations are given to illustrate how these principles are applied for the commercial separation of sulphide minerals from their ores. Various novel techniques that take advantage of controlling the electrochemical and physical behavior of the flotation system are also presented.

Choose the correct statement(s) for froth flotation

In some sulphide ores of copper, zinc and lead, the concentration is brought by froth flotation process. In this method, the advantage is taken of the preferential wetting of the ore by an oil. The finely ground ore is taken in a tank containing water and 1% of pine oil or turpentine oil.

Sulphide Gold Ore Treatment by Leaching and Flotation

Problem with gold recovery from sulphide ore: How may a mill get the maximum recovery of gold from a sulphide ore, at the least capital cost and at the same time obtain the highest net return. This latter point is most important. In many cases a gold mill using an all-cyanide flowsheet with fine grinding of all the ore will report very low gold content in the tailings particularly on an

Rougher flotation of copper sulphide ore using biosolids

01/11/2011· Froth flotation is a physicochemical process that has been used for more than a century in the concentration of copper sulphide minerals (Herrera-Urbina, 2003). This process is based on the wettability of mineral particles to recover the mineral species of interest and depress unwanted gangue.
