The use of a comparatively new flocculating agent C.M.C. Carboxel, or sodium carboxymethylcellulose, is described by E. E. Brown, mill superintendent of the Chesterville Mines, Ltd. A water-soluble "H.V." grade used in the amount of 0.01 lb. per ton of ore increased the settling rate in the thickeners by 8 to 10 per cent.
Processes: copper mining and production. Copper is found in natural ore deposits around the world. This page explains copper mining: the production route taken from ore-containing rock to a final product that is the highest-purity commercial metal in existence and used in a wide variety of applications essential to modern living.
Only the flotation process mentioned above could make this practicable; and even so, it requires large companies with huge plants, continuous working and immense capital. This explains why, in order to smelt 4 million tons of new copper in 1963, nearly 400 million tons of ore …

The process used to treat sulfide copper ores begins at the mine site, where the copper-bearing minerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining.
Answer (1 of 2): Copper is extracted from various sulfide ores. The most common are bornite and chalcopyrite, the others include tetrahedrite, native copper, covellite, chalcotite and some even more uncommon. Copper can be theoretically extracted also from secondary copper minerals like malachit...
Figure 1: Overview of copper production Benefication process Figure 2: Overview of a typical beneficiation process at a concentrator Sulfidic copper ores are too dilute for direct smelting. Smelting these materials would require too much energy and very large furnace capacities. The copper ore coming from the mine (0.5 – 1 %
Copper Mining Thickening In Mineral Processing. Copper Mining Thickening In Mineral Processing. Copper processing is a complicated process that begins with mining of the ore less than 1 copper and ends with sheets of 99.99 pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two ...
Beginners guide to thickeners. Thickening is a process where a slurry or solid-liquid mixture is separated to a dense slurry containing most of the solids and an overflow of essentially clear water (or liquor in leaching processes). The driving force for the separation is gravitational, where the differences in phase densities drive the ...
The underflow gangue (waste) from the rougher and scavenger cells flows to a tailings thickener to recover water for the process. Filters dewater these tails further, or a tailings pond stores them. Bulk (Copper-Moly) Thickener. A high-rate thickener dewaters the bulk of copper-moly concentrate before more separation. Moly Flotation
To be more specific, let us take the example of a copper ore whose grade, or copper content, is only 1% by weight. Let us assume that the sole copper mineral species in this ore be chalcopyrite, which is one of the most popular copper minerals found in copper ores in our planet. The chemical formula of chalcopyrite is known to be CuFeS2.

thickening For copper sulfide ore a stage in the process of pyrometallurgy in which the copper froth from the froth floatation stage is poured into large tanks called thickeners where the copper solids settle and are filtered to remove excess water this copper concentrate will then undergo smelting. Different Thickening Process In Iron Ore ...
2. In copper processing, a copper anode is an intermediate product from the smelting furnaces which is used as a copper source from which to make copper cathodes during electrolysis. aqueous Of or containing water, typically as a solvent or medium; i.e., an aqueous solution. cation
Water is usually reclaimed from the thickeners and recirculated to the mill to be used in beneficiation and dust control (Mining Industry Profile: Copper) Spent Ore from Heap, Dump, and Vat Leaching Spent ore consists of the material remaining in either dump or heap leach piles when leaching ceases.
Thickeners. The separation of solids from a liquid by gravity sedimentation has traces to the early days of civilization. The normal practice at those times was to use jars or pits mainly for the clarification of extracted liquids such as wine or olive oil from contaminating insoluble matter.

mans found nearly 100 lens-shaped ore bodies in the Rio Tinto copper district. Modern geologists have found only a few additional deposits, and almost all of Rio Tinto's modern production has been from ore first discovered by the Remans.3 At Rio Tinto, the Remans mined the upper, ox-idized, part of the ore and collected the copper-
Historically thickeners were introduced to the mining industry in 1905 when the beneficiation of ores by froth flotation was invented in Australia. In 1964 there was a project to reprocess the huge piles of tailings that accumulated over the years and recover the remaining copper .

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).
Thickeners and clarifiers are both used to separate liquids and solids by settling. Clarifiers can be circular clarifiers, pictured on the left, or parallel plate Adjustable rake arms increase operating efficiency by reducing maintenance downtime. the uranium industry, and in alumina, coal, copper, and iron ore …
precipitate copper onto iron (Arbiter and Fletcher, 1994). This process became known as the "cementation process", which is apparently derived from the Spanish word "cementación", meaning precipitation. Over the next three centuries, it was the primary method used to recover dissolved copper from dilute leach solutions, before being
Copper oxide ores undergo a three-step process to achieved high levels of concentration. First, in a process called heap leaching, sulfuric acid is used to separate copper from the ore. Next, the solvent extraction stage moves the copper from the leach to a solvent, removing impurities. Last, electrowinning involves passing an electric current ...

The process can involve crushing the ore and then binding it, or the ore can be directly placed on the heap or leach dump, where the lixiviating solution percolates through the ore to release the copper ions into solution. If agglomeration is used the sulfuric acid starts to dissolve the copper from the minerals.
