Flotation Process of Copper Sulfur Ore 1. Priority flotation. Generally, the copper is first, and then the sulfur is floated. The pyrite content in the ore is relatively high for massive copper-containing pyrite. High alkalinity (free CaO content >600~800g/m3) and high xanthate dosage are often used to suppress the pyrite by floating copper.
Due to the different types of ore, the nature of the ore is also different, so the beneficiation process needs to be customized. The specific process for selecting copper ore depends mainly on the material composition, structure and copper occurrence state of the original copper ore. Generally speaking, copper ore can …
By example a typical copper concentrate may have a TML of 9% moisture.

The use of power ultrasound in mining. L. Gaete-Garretón, in Power Ultrasonics, 2015 35.5.1 The flotation process. One of the most used processes to concentrate mineral from a mine is flotation. To perform a flotation process the mineral is finely ground (particle sizes between 50 and 150 μm), then the ground mineral is mixed with water in a container called a flotation cell.
This paper presents a review of chemical composition data of the main stages of copper production from sulfide minerals, such as (1) copper minerals, (2) flotation tailings, (3) flotation concentrates, (4) slags and (5) flue dust from the smelting/converting stage, (6) copper anodes, (7) anode slimes, (8) contaminated electrolytes from the ...
Most copper ore currently being mined contains copper mainly as chalcopyrite. Since chalcopyrite by itself is only about 35 percent copper, it is difficult to upgrade a concentrate by flotation to more than about 25 to 28 percent copper without losing a significant amount of copper during the cleaning steps.
About 80 % of primary copper production comes from low-grade or poor sulfide ores. After enrichment steps, the copper concentrates are usually treated by pyrometallurgical methods. Generally, copper extraction follows the sequence (see Figure below): 1. Beneficiation by froth flotation of ore to give copper concentrate
Thus in an ore containing both sulphide and oxide copper the recovery credited to the process should be based on the sulphide copper content of the feed, concentrate and tailing, if a true measure of the efficiency of the process is sought. Froth-flotation, properly practiced, will recover from 60 to well over 95 per cent, of the sulphide ...
After secondary flotation the concentrate is sampled and sent to a thickener, where froth bubbles break and the copper minerals settle to the bottom of the tank. ... Multotec specialises in process equipment used in copper …
Copper ore must undergo a complicated refining process to convert it into saleable high-purity copper products, as mined ore typically contains less than 1 percent copper.Copper refining involves ...
ACID LEACH RESIDUE FLOTATION CIRCUIT — This circuit consists of three banks of 6-cell Agitair flotation machines for rougher flotation and one bank of 3-cell Agitair flotation machines for cleaning flotation.

Copper concentrates are widely used in smelting operations worldwide and typically consist of chalcopyrite (CuFeS2) as the primary mineral, with chalcocite (Cu2S) and bornite (Cu5FeS4) as secondary copper-bearing minerals. However, these concentrates often contain hazardous impurities, such as the fluorine ion, which can result in various complications during …
