Production process was using by the process of grindingflotation. After grinding fineness, lime dosage, sodium sulfide dosage, collector and frother dosage, were determined by the open test. Closed circuit experiment was conducted by those optimal conditions identified in the above test, the recovery of copper concentrate is % and the grade of copper concentrate is %.
Turnkey flotation retrofit with fast turnaround for Yamana Gold in Brazil. Outotec delivered an extremely fast turnaround, minimizing production losses and increasing recovery while improving the availability and energy efficiency of the flotation cells.
flotation process in the recovery of copper from copper ... Copper Sulphide Ore Flotation Process Xinhai. The copper concentrate grade that obtained by flotation process in China is over 20%, the recovery rate is about 88%; the foreign copper concentrate grade is about 25~40%, the recovery rate is 80~90% Generally, the flotation process of copper sulfide ore is relatively simple
Rougher flotation in sulfide ore applications is typically performed using conventional flotation machines. The trend over the last 100 years has been for these cells to become larger in volume with cells reaching sizes of 600 m3 and in some cases even larger.
Copper sulfide ores must be concentrated before they can be economically transported to a smelter. Froth flotation is part of a copper beneficiation process in which finely ground ore is placed in aerated tanks that contain a waterbased solution from which a coppersulfiderich froth is recovered (PDF) A Review of the Flotation of Copper Minerals
On your tour, you'll see how copper ore is mined in the openpit and then at the center ... tickets for the tour and become familiar with the copper mining process in our ... so the copper minerals can be separated by the froth flotation process.
in the flotation recovery of molybdenum and copper from their porphyry sulfide ores. One is the bulk copper− molybdenum flotation followed by separation, which has been widely used in several largescale mines such as Dexing copper mine (Jiangxi Province, China) [2]. This approach has an uncomplicated technological process
New Reagent System Improves Recovery, Reducing Energy Use and Air Emissions in the Mining Industry. It flocculates fine material and may occlude fine coppersulfide particles. Lime increases the viscosity of the mineral slurry and tends to hinder aeration, slowing flotation kinetics. In addition, the calcium ion also has been shown to decrease recoveries of lead and molybdenumsulfides and to reduce the recovery .
Nov 09, 2016· Coppergold sulfide ore flotation process be addressedThe first paragraph flotation recovery of the goldbearing sulfide, From Ore to Finished Product copperorg Processing of Copper Ore The next step in the process flow is smelting for sulfide ore concentrate and solvent extraction for oxide ore leach solution 6
Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry.
Oct 01, 2000· Read "Improving flotation recovery of copper sulphides by nitrogen gas and sulphidisation conditioning, Minerals Engineering" on DeepDyve, the largest online rental service for scholarly research with thousands of academic publications available at your fingertips.
copper ore using flotation followed by atmospheric and highpressure oxidative leaching. The effects of various flotation parameters, such as flotation time, PAX dosage, slurry pH and air injection rate on beneficiation of copper from the lowgrade copper ore were studied. The recovery of copper reached
Mar 08, 1977 The method of recovering copper by froth flotation from an aqueous pulp of an ore containing both sulfide and oxidized minerals of copper which comprises subjecting an aqueous pulp of the ore to a first froth flotation operation in the presence of a collector for sulfide copper minerals, thereby producing a concentrate containing a large ...
flotation tests were unsuccessful in terms of both recovery and grade of concentrate product. The highest copper recovery of concentrate was found as % with % copper content. The concentrate with highest copper grade of % was obtained with only % copper recovery. Unsuccessful flotation of the test
In general, the conventional flotation methods of copper sulfide ores do not apply to oxide ores. Flotation with fatty acids or surface sulphidisation of copper oxide minerals and their subsequent flotation using sulfhydryl collectors are two main methods for the Cu recovery from oxide ores.
After the exploring test of principle flow sheet, the flotation process of depress lead and float copper is used. As a result, the grade of copper is % and lead is % in the copper concentrate, the grade of lead is % and copper is % in lead concentrate.
significantly affected copper recovery whilst pH was found to also significantly affect cobalt recovery. Keywords: flotation, process optimization, Taguchi orthogonal array, ANOVA. 1. Introduction Froth flotation is widely used for separating base metal sulphide minerals in complex ores. One of
Improving copper flotation recovery from a refractory . Lime is commonly used as a pH regulator and depressant against iron minerals during the flotation recovery of copper minerals from copper porphyry sulfide ore. It can also depress copper oxide, secondary copper sulfide or gold minerals ( Allan and Woodcock, 2001, Sun, 2001, Liu et al., 2008a ).
All the flotation testwork was done using the Denver laboratory machine with a stainless steel flotation cell. The required mass of nickelcopper sulphide ore material ground to 70% passing 75 µm was weighed and placed in the flotation cell.
12. Flotation of Copper Sulfide Ores different frothers on ores containing montomorillonite and illite clay showed that the frother type had a significant effect on the rate of copper flotation and recovery. This effect is illustrated in Figure The HP700 frother gave the best results.
A process for recovering molybdenite from feed materials containing copper sulfide and molybdenite ( copper/molybdenum concentrates from flotation processes) wherein the feed material is treated with ozone and then floated to recover molybdenite.
Apr 23, 2011· Copper sulfide ores. Secondary sulfides formed by supergene secondary enrichment are resistant to sulfuric leaching. When rich enough, native copper ore bodies may be treated to recover the contained copper via a gravity separation circuit. Supergene ores rich in sulfides may be concentrated using froth flotation.
