Froth flotation - Wikipedia

Froth flotation is a process for selectively separating of hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

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 ...


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. To meet the froth flotation requirements, the concentration of pulp can be adjusted by adding the required water and flotation agents.


After carrying out a froth flotation separation, the products are as shown in Table 1. Using this data, calculate: (a) Ratio of concentration (b) % Metal Recovery (c) % Metal Loss (d) % Weight Recovery, or % Yield (e) Enrichment Ratio Table 1: Grade/recovery performance of a …


More 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:


Do you know the pulp density of the mill? Seems like they used to recommend 70% solids for the best combination of grind versus the wear on the media and lining. ... This is a small plant flotation froth that I am implementing and milling capacity is 1.8 tons / day. ... Am adding copper sulfate 80 g / ton to the output of the mill and the pump ...


The flotation feed was ground to d 80: 38 µm in a ball mill at 60% w/w pulp density. The flotation tests were carried out at 30% pulp density using a 4.5 L Denver flotation cell. In the flotation plant, a proprietary blend collector Kimfloat900 (150 g/t), a thionocarbamate formulation, was used in the copper flotation circuit at pH 11.5–12.

An improvement in the froth flotation separation of metallic sulfide mineral ores, particularly those ores bearing copper and molybdenum, in which a mercaptan collector is used in an earlier primary flotation stage, the improvement comprising the addition of activated carbon to achieve deactivation of the mercaptan collector prior to the component mineral separation stage, thereby providing ...


Quite simply stated, if the pulp density is not maintained at 30% or higher by weight, it is very difficult to keep the coarser free gold into the froth phase. Copper sulfate is often used as an activator for promoting free gold flotation. Often in plants using CuSO4, it has been this author's experience that this activation has not been ...


The effect of pulp density on copper and iron HPL from the concentrate of flotation tailings was investigated under the following conditions: H 2 SO 4 concentration of 0 M and a total pressure of 2.0 MPa at a temperature of 180 °C for 60 min, …


Froth flotation, is a physicochemical method of concentrating fine minerals and coal. It can be stated that Flotation is a physiochemical separation process that utilises the difference in surface properties of the valuable minerals and the gangue minerals. E.g. …

Lead, Zinc ... with a copper grade ... Know More. Example Copper Flotation Flowsheets | Mining & Metallurgy ... in many copper and zinc flotation plants.


RECOVERY OF COPPER FROM OXIDE COPPER ORE BY FLOTATION AND LEACHING Kiraz, Emirhan M.S., Department of Mining Engineering Supervisor: Prof. Dr. Mustafa Ümit Atalay December 2014, 65 pages The aim of this study was the recovery of copper from the oxide copper ore by froth flotation and agitating sulphuric acid (H 2 SO 4) leaching.


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.


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 ...
