Appliion Of Copper Ore Concentrate Ore Pulp

Copper Ore an overview ScienceDirect Topics

W.G. Davenport, in Encyclopedia of Materials: Science and Technology, 2001. 1.1 Physical Beneficiation. Beneficiation of copper ores is done almost exclusively by selective froth flotation. Flotation entails first attaching fine copper mineral particles to bubbles rising through an ore–water pulp and, second, collecting the copper minerals at the top of the pulp as a briefly stable mineral

Copper Concentrate an overview ScienceDirect Topics

Some of the typical processes include the extraction of metals from various types of iron ore to hot metal and from hot metal to steel; from copper concentrates to pure copper; and from aluminum scrap to pure aluminum or its alloys. These processes are generally complicated because of their multi-phase, high-temperature, and highly reactive characteristics. The complex phenomena of flow, heat

Froth flotation Wikipedia

His "Bradford Ore Separator," patented 1853 and subsequently improved, was used to concentrate iron, copper and lead-zinc ores by specific gravity, but lost some of the metal as float off the concentration process. The 1886 patent was to capture this "float" using surface tension, the first of the skin-flotation process patents that was eclipsed by oil froth flotation. It is uncertain if his

Metal Production from Concentrates Aurubis

Copper ores contain about 0.5-4 % copper and are already processed into a concentrate in the mine. The concentrate is a finely milled, dark gray material containing about 30 % copper (Cu), 30 % iron (Fe) and 30 % sulfur (S). The concentrate also often contains small amounts of precious metals and a range of other elements, which we process in the smelters.

Extraction of metal values from ores or concentrates

Application Number: 07/058607 . Publication Date: 04/18/1989 An example of such a process is one in which the ore or concentrate is, for example, a copper ore, such as a copper-bearing pyrite, in which case the aqueous liquor from the separation step can be subjected to conventional copper recovery techniques, such as cementation, whilst the leached solids are discarded. The barren ferrous

Gold and copper leaching from gold-copper ores and

1/5/2017· The following sections cover the gold and copper extraction from ores and gold, silver and copper extraction form a concentrate. 3.2. Gold-copper ores: gold-copper oxides. The gold extraction from leaching gold-copper oxides ore, containing 12.9 ppm gold and 0.04% copper, has been studied. The copper in such ore is present at nuisance levels

Copper Mining and Extraction Sulfide Ores

The froth is skimmed off the surface and the enriched ore (mainly the copper mineral) is taken away for roasting. The mixture of water, foaming agent and paraffin is recycled. After this stage the enriched ore now contains about 25% copper by mass and is called copper concentrate. It is valuable enough to ship to other plants and other

Pulp Density Temperature Flotation Table 1: Grade/recovery performance of a hypothetical copper ore flotation process. Product % Weight % Cu Assay Feed 100 2.09 Concentrate 10 20.0 Tailings 90 0.1 (a) From Table 1, the Ratio of Concentration can be calculated as F/C = 100/10 = 10. If only assays are available, the ratio of concentration equals (20 0.1)/(2.09 0.1) = 10 So, for each

APPLICATION OF MODIFIED SULFIDIZING REAGENT (MSR) IN

The pulp with ore reduction (71 %) 0,071 mm was floated in the laboratory flota-tion machine with chamber volume of 0,5 lunder an open scheme: L:S (liquid/solid) = 3:1. Butyl potassium xanthate was used as a collector, and foaming reagent T 92. All experiments showed the identical flotation mode. Copper extraction in flotation products was de-fined with using the data of the chemical

Electromagnetic flow measurement in mining and

The Erdenet Mining Corporation is one of the largest ore mining and processing factories in Asia. It started operation in 1978 and is a joint venture between the governments of Mongolia and Russia. The main mineral deposit, extracted by the Corporation is Erdenetiin-Ovoo area, 400 km northwest of Ulaanbaatar. At present, it is a fairly large complex processing 25 million tons of ore per year

Copper Steencore Mining & Energy

Used as raw materials in copper smelting. Copper concentrates are mostly from sulfide ores. Ores extracted from overseas mines have a typical grade of about 1%. The ores are processed at the mines to increase the Cu content for concentrate. COPPER ORE CONCENTRATE OF 22% ~ 25%
