The molecular form of aliphatic amines precipitates in alkaline solutions when the amine solubility limit is exceeded and forms a typical colloidal system. The zones of mines precipitation and micellization are defined and it is shown that the appearance of a colloidal system in a certain pH range is a unique feature that makes weak electrolyte type surfactants differ from strong …
Its natural floatability is good, so froth flotation is the main method of extracting copper ore. According to the processing order of the useful mineral, the copper ore processing/mining can be divided into precedence flotation, equivalent flotation, mixed flotation, and partial flotation.
This is an article in the field of mineral processing engineering. The gold mineral in an arsenic bearing high sulfur gold mine has a close symbiotic relationship with pyrite and arsenopyrite, and the recovery rate of concentrate gold is not ideal in the actual production process. In order to improve the recovery rate of concentrate gold and take into account the grade of concentrate …
When tailings undergo a flotation step, the system boundary includes their transportation from the mine to the REE processing facility, the beneficiation – which is …
Bentonite and kaolin caused different issues in copper flotation. Bentonite reduced the amount of froth and decreased copper recovery. Kaolin enhanced froth stability and …
the flotation mechanism lies in exploiting these differences, allowing for a selective and efficient separation process based on the tendency of minerals to adhere to either water or air bubbles. 2.1. Description of the Floatation Process The flotation process occurs in the aquatic environment within dedicated flotation
In this study, sulfate as an anion with different types of cations, Na+, K+, Mg2+ and Ca2+ were used to reduce bentonite viscosity and to improve flotation performance. It was …

He said that coarse particle flotation could allow mines to reject some waste earlier in the value chain, which will help reduce capital and operating costs. WATCH: An introduction to the staged flotation reactor. Unfortunately, the conventional flotation cell achieves high recovery only in limited size ranges. For example, a sulfide ore might ...
In this study, the effect of cations, Na+ and Mg2+, in saline water on copper flotation in the presence of calcium bentonite was investigated. It was found that as the …

In flotation, pH control is a vital method to control selective mineral separation. A standard depressant that is used is an Alkali. An Alkali is any substance that when mixed with Acid will neutralize each other and form a …
On January 25, 2019, the tailings dam at Vale's Córrego do Feijao mine (Brumadinho, Minas Gerais, Brazil) ruptured, releasing about 12 million cubic meters of tailings, killing over 240 people and posing a considerable and ongoing environmental hazard. Thus, the recovery of valuable minerals from tailings can contribute to a sustainable disposal of this hazardous residue, …
1. Introduction. Acid mine drainage (AMD) is one of the most serious environmental issues facing the global mining industry. AMD is primarily formed by the oxidation of sulphide minerals exposed to air, water, and microbial activity, and is mostly derived from active or abandoned polymetallic sulphide mines as well as coal mines (Levio-Raiman et al., 2021; …

(4) treatment of the slag by flotation. Flotation appeared to offer the most promise for economical recovery of the copper. The Bureau of Mines made flotation and grindability tests on three converter slags containing 1.6 to 6.6 percent copper. The relative merits and costs for the flotation of slow-cooled versus water-quenched slags were ...
Since human daily demands for fresh water have been increased significantly, the supply of fresh water for the mining industry, especially froth flotation, should be considerably reduced. In addition, stricter environmental standards have been implemented in many countries to reduce the risks due to the disposal of wastewater, many flotation operators have to seek …

A classification of flotation processes carried out in concentrated electrolyte solutions, e.g., seawater, is proposed using the most obvious features of these processes: low or high content of Mg2+ and Ca2+ ions, pulp ionic strength, and pH. The first distinguishable group is the processes carried out in NaCl/KCl solutions, about 0.5 M in the case of salt flotation of …
After each flotation experiment, the concentrate and the tailing were filtered, dried, and weighed. Flotation recovery (R) was calculated using Eq.2. (2) R = m 1 m 1 + m 2 × 100 % where m 1 and m 2 are the mass of the floated and un-floated fractions, respectively. Each flotation experiment was repeated three times and the reported values were ...
