Flotation is widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores. Many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation process. This article was most recently revised and updated by Chelsey Parrott-Sheffer, Research Editor.

Rice UNITED STATES DEPARTMENT OF THE INTERIOR Bruce Babbitt, Secretary BUREAU OF MINES This report is based upon research conducted under an agreement between the University of Alabama and the Bureau of Mines. ...
A bulk flotation process followed by a reverse flotation where copper was depressed and lead was floated from the bulk concentrate also produced separate concentrates, but at lower efficiency than the sequential circuit. flotation plant of copper concentrate. flotation concentrate
The production of concentrates implies the crushing and later milling of the ore down to a particle size allows releasing copper by flotation. The concentrates from different regions have approximately between 24 up to 36 of copper. Copper concentrates are then submitted to a final filtration and drying process to decrease the humidity to 8-9.
Namibia Custom Smelters NCS process a range of copper concentrates in their three furnaces, namely top submerged lance, copper converter and reverberatory furnaces, in order to produce mattes and fayalitic slags. The copper content of the slags range between 0.8 to 5 wt. and this is considered

A hydrometallurgical process for the removal of arsenic and antimony from a so-called dirty copper concentrate 101 is described. The process comprises the following steps Step 1 repulping 100 the dirty copper concentrate with an alkaline lixiviant 102, 103, and subjecting the dirty copper concentrate to an alkaline leaching process the Leach in a Leach reactor 110.
The ore is mined from an open pit, crushed, and fed to ten ball mills. The concentrator is divided into two parallel comminution-flotation sections, so that five ball mills feed each flotation section. Both sections consist of three bulk copper and molybdenum rougher flotation lines, and the rougher concentrate is transferred to a regrinding stage.
Flotation of grinding products with 55, 60, 65, 70, and 75 of grain size 74 m, was conducted at the pulps pH values of 10 and 12. Higher copper recovery was obtained in concentrates at pH 10, b...
Aug 01, 2020 1. Introduction. Copper is one of Australias top commodity exports, hosting the worlds largest iron oxidecoppergold IOCG deposits. However, uranium and its radioactive decay radionuclides are enriched in IOCG ores due to a strong association of uraninite UO 2 with Cu Fe sulphides and iron oxide hematite, Fe 2 O 3, which are impurities in the copper flotation concentrate.
Flotation of copper sulphides is a traditional technique for processing the sulphide copper. The presence of pyrite in copper concentrates especially the pyrite particles that are surrounded with the chalcopyrite is the most important problem of copper ore processing that leads to a decrease in the quality and grade of concentrate. ...
Copper concentrates. Used as raw materials in copper smelting, copper concentrates have a copper content of about 30 by weight. The remainder consists mostly of sulfur and iron. Copper concentrates are made mostly from sulfide ores. Ores extracted from overseas mines have
This means that 95.7 of the copper present in the ore was recovered in the concentrate, while the rest was lost in the tailings. c The Cu Loss can be calculated by subtracting the Cu Recovery from 100 Cu Loss 100 95.7 4.3 This means that 4.3 of the copper

The texture of particles within a flotation cell play a pivotal role in both mineral recovery, and the grade, in the flotation concentrate. Theoretical curves can be generated based on particle mineralogy and texture to indicate the maximum grade-recovery possible for a given feed ore.
