Surface oxidation of secondary minerals, such as chalcocite, bornite and digenite, present in the Salobo copper ore makes their flotation difficult and requires excessive reagent consumptions.
In the extreme, the flotation cells "boiled" because the pulp was too viscous for the air to be dispersed. Download: Download full-size image; ... Inco Limited, Manitoba Division — The Thompson Mill.

2.2. Development of the In-Pulp optical measurement apparatus. The flotation pulp samples were fit into a 10 mm × 10 mm × 45 mm cuvette. The total mass for each sample was about 3 g with the samples split to −38 µm (fines) and + 38 µm (coarse) as the fines and slimes obscured the optical microscopy images when combined.
A large porphyry copper flotation plant has been simulated using a flotation model developed from first principles using the hydrophobic force as a kinetic parameter (Huang et al., 2022, Gupta et al., 2022).The input to the simulation was the size-by-class liberation matrix (m ij) of a flotation feed, which was essential for predicting the size-by …
The flotation by surface sulphidisation of the oxidized copper-cobalt-bearing ore from Kimpe (1.97% Cu; 0.66% Co) was studied in order to evaluate its behavior by the analysis of its most ...

This paper discusses the effect of wet and dry grinding on copper flotation of a complex Cu-Pb-Zn ore. Industrially, wet grinding is preferred due to its higher energy efficiency and owing to ...
The basic factors, principles and variables affecting froth flotation are enumerated in condensed form below: Ore. (a) Mineralogical character. (b) Fineness of grinding. (c) Method of grinding. Agents. (a) Principal flotation agent. ("Oil") α Character. β Quantity. (b) Minor agent. α Character. β Quantity. Water. (a) Quantity with respect to …
Inside the flotation cells, the ore pulp processed with reagent is mixed and inflated with air to make some ore particles selectively adhere to the bubbles. Then the bubbles will float to the surface of the ore pulp and be scraped out to become froth pulp and the rest will remain in the ore pulp, thus reaching the aim of separating the minerals.
This study investigates a technique utilising deep learning machine vision and optical microscopy for in-pulp characterisation of mineralogy and particle size …
(5) The left pulp that are not sucked by the impeller enters intor the third tank after going through the process of the first tank, thus, flotation machine for ore runs in cycle and discharges ore pulp through the tailing box of the flotation machine. 4.

A few studies report the use of rhamnolipid biosurfactants as frothers in copper ore (Khoshdast et al., 2012b) and in coal (Khoshdast et al., 2011, Khoshdast and Sam, 2011) flotation processes, indicating that the use of rhamnolipid surfactant significantly increased the flotation rate of all minerals. Also, the collected interfacial …
With higher concentration rates and a simple and efficient flowsheet, the FCSMC has been successfully industrialized for flotation circuits of minerals such as coal and copper ores in China. 21−23 However, there have been relatively few studies on the flotation behavior of columns and cells in gold mineral flotation, particularly concerning …

Figure 1 is a generalized diagram of a conventional copper flotation plant from the point where ore first enters the circuit to the production of concentrate and tailings. To prepare ore for the flotation process, run-of-mine ore, which may contain from about 2 to 5 percent water, by weight, when mined, is
