specifically, the improved process is a method for recovery of metal values by froth flotation from metallic sulfide mineral ores comprising copper and molybdenum, including the steps of (A) forming an aqueous mineral pulp from the ore.
Dec 26, 2018 In addition to maintaining a steady froth bed, froth level control has helped in stabilizing the zinc rougher-cleaner circuit, especially when there is a variation in head grade or after rodding or a shut-down. Testing of frothers is also greatly simplified. The pulp density meter is based on the principle, also used in the well-known bubbler.
The particle size of the particle and the froth stability, viscosity and pulp density during the process relevant factors during the process in the copper concentration process by flotation [2-5] Generally, flocculants and peptizes during flotation are applied to allow clays to be included into the pulp in suspended form. This reagent can promote the precipitation of the ore and generate losses during the process.
Basic Principle of Froth Flotation Process. The process of froth floatation starts with the Comminution process in which the surface area of the ore is increased. First of all, the ores are crushed into very fine powder sized particles and mixed with water. The mixture obtained is called Slurry.
The effect of flotation feed density on metallurgical performance has been investigated. Results of test work have shown that the pulp density affects key parameters of the flotation process in both the pulp and froth phases (Runge et al., 2012). One of the findings was that froth.
What I claim as my invention is 1. A process for the flotation recovery of copper values from ores containing copper values in the form of at least one sulphide copper mineral and at least one sulphuric acid soluble copper mineral using a sulfhydryl anionic collector comprising subjecting a pulp of the ore to acid treatment by conditioning the pulp with addition of an acid agent, the acid.
Jun 15, 2018 To achieve an excellent copper dissolution from the concentrate of flotation tailings, which consist of chalcopyrite as the major copper component, high‒pressure leaching (HPL) was conducted using an autoclave under a variety of sulfuric acid concentration (0–0.5 M), total pressure (0.8‒2.0 MPa), temperature (140‒180 C) and pulp density (100‒400 g L).
Sep 20, 2019 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.
The flotation is done in large 10100m 3 cells whose principal functions are to provide clouds of air bubbles to which the copper minerals of the pulp attach a means of overflowing the resulting bubblecopper mineral froth and a means of underflowing the unfloated material into the next cell or to the waste tailings area.
Apr 17, 2019 Froth flotation is the use of the physical and chemical properties of the surface of the ore, the use of chemical separation of useful ore. In the process of froth flotation, useful minerals are separated by floating them in the foams, and the way of keeping gangue minerals in the pulp is called positive flotation, while the way of floating gangue minerals in the foam is called reverse flotation.
EXAMPLE 1. Froth Flotation of a South African Gold Ore. A weighed amount of South African gold ore was ground in water to provide a pulp of the ore having a grind size of 70 minus 200 mesh and a pulp density of 38 solids by weight or specific gravity of 1.32.
Froth flotation is a widely used process of particle separation exploiting differences in surface properties. It is important to point out that overall flotation performance (grade and recovery.

Product Weight Cu Assay Feed 100 2.09 Concentrate 10 20.0 Tailings 90 0.1 (a) From Table 1, the Ratio of Concentration can be calculated as F C = 100 10 = 10.
Are stirred into the pulp, rise with them to the surface of the pulp, and are skimmed off as a froth of fine concentrate. The hydrophilic gangue minerals remain in the pulp. Organic reagents with sulfur-containing groups at their polar end, such as xanthates, are used as collectors in the flotation process.
FROTH FLOTATION RECENT TRENDS @IIME, JAMSHEDPUR, 1998 pp. 18-41 Flotation of Sulphide Ores - HZL Experience V.P. KOHAD Hindustan Zinc Ltd., Zawar Mines, Udaipur - 313 901 ABSTRACT Flotation process, patented in the year 1906, was originally developed for mineral industry to recover values from high grade tailings of gravity separation plants.
Feb 06, 2020 As the common mineral processing process, the froth flotation process is widely used in the concentrator. Because the froth flotation process is strict with grinding fineness, pulp density, flotation reagent, the flotation plant operators must inspect the flotation conditions during the operation of the flotation machine.
2. The method of controlling the course of a froth flotation operation wherein a continuous flow of air is delivered into a pulp of finely ground ore in a flotation cell, and an aqueous pulp of flotation concentrates is continuously discharged from said cell, which comprises continuously measuring the volumetric rate of flow and the density of.
Dec 20, 2018 The most suitable ore pulp concentration during the flotation process is related to the ore property and the flotation processing conditions. The general rules as flow (1) Pulp Density. The mineral with large flotation density uses a thicker slurry, while the mineral with a small flotation density uses a thinner slurry.
The present study focused on the re-processing of copper and nickel from mine tailings. In this work, recovery of copper and nickel from mine tailing by combined process of flotation and high pressure oxidative leaching were considered. In the first stage, effects of flotation parameters including collector type, collector dosage, and pH and pulp density were examined.
Jul 11, 2016 Flotation Tests with Homemade Flotation Equipment DIY. By modelling the basic flotation equipment from the early 1900’s you see that most can hobby prospectors can build or assemble basic froth flotation equipment using all the machines and concepts explained below and perform home-based flotation tests. Although the subject of testing for.
Copper sulfides hydrophobic and capable to create the froth . Then, the pulp is transported into flotation machines, where froth with beneficiated ore is collected and sent to drying process as concentrate. The tailings are processed in a similar way in consecutive flotation stages until they reach low content of copper (less than 0.15 ).
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.
The froth flotation process of coal slime was studied by the flotation experiments on the coal slime of Qian yingzi, Pan yidong and Qidong coal preparation plant. The influence of coal slime properties, collector dosage, ratio of collector and frother, and pulp density on the flotation effect were studied. The experimental result showed that the coal slime with rich fine and high ash fraction.
