View the report, TENORM in SW Copper Belt of Arizona, on the TENORM Resources webpage. Smelter Slag. Smelter slag is initially deposited in piles. These slag piles range in surface area from one to 75 acres, and in height from three to 45 meters. Slag is associated with smelter operations, which may or may not be co-located with the mines.
In recent studies, gold distribution coefficients between copper and slag in copper—silica-saturated iron-silicate slag system (1300 °C, pO 2 = 10 −4 – 10 −8 atm) were measured as 10 5.5 – 10 7 and in matte-copper-slag-tridymite system (1200 °C) between 10 5.3 and 10 6 . These are in excellent agreement with our results.

copper processing - copper processing - Roasting, smelting, and converting: Once a concentrate has been produced containing copper and other metals of value (such as gold and silver), the next step is to remove impurity elements. In older processes the concentrate, containing between 5 and 10 percent water, is first roasted in a cylindrical, refractory-lined furnace of either the hearth or ...
Extraction of Copper. It is mainly extracted from copper pyrites (CuFeS 2). The sulphide ore is usually of very low grade and contains iron sulphide, gangue and smaller quantities of arsenic, antimony, selenium tellurium, silver, gold and platinum. The various steps involved in the extraction are: 1) Crushing and concentration
A hydrometallurgical process for treating slag material, especially copper smelter slag material, comprises vigorously mixing the slag material with about one part by weight of sulfuric acid and about one part by weight of water for each part by weight of the slag material, and allowing the resulting mixture to react to produce a dry, solid material, containing the metal values of the slag in ...

Copper is produced in the U. S. primarily by pyrometallurgical smelting methods. Pyrometallurgical techniques use heat to separate copper from copper sulfide ore concentrates. Process steps include mining, concentration, roasting, smelting, converting, and finally fire and electrolytic refining. 12.3.2 Process Description2-4
12%For the slag containing 20 wt % iron oxide, at T = 1423 and 1523 K, the viscosity equals 0.675 and 0.276 Pa s, respectively. Upon a fourfold recycle of the copper collector, the gold concentration in it increased to 19.8%, silver to 2.16%, platinum to 1.08%, and palladium to 0.9%.
higher absorption capacity than air-cooled copper slag. The granulated copper slag is made up of regularly shaped angular particles, mostly between 4.75 and 0.075 mm3. Slags produced during pyrometallurgical processes have been traditionally considered as a waste3. In the case of copper extraction processes, it has been estimated that for every ...
Gold ore. Prominer maintains a team of senior gold processing engineers with expertise and global experience. These gold professionals are specifically in gold processing through various beneficiation technologies, for gold ore of different characteristics, such as flotation, cyanide leaching, gravity separation, etc., to achieve the processing plant of optimal and cost-efficient process designs.
Concentration means increasing the amount of gold in ore or sediment, by selectively removing lighter particles. If employed effectively, concentration methods can eliminate or greatly reduce the need for mercury. Before concentration can begin, ore must be crushed or milled to liberate gold particles from rock and to decrease grain size.
The products are (i) a molten copper-iron-sulphide matte with approximately 65% copper concentration, (ii) molten iron-silicate slag containing 1-2% copper and (iii) hot dust-laden off gas ...
Minerals are concentrated into a slurry that is about 15% copper. Waste slag is removed. Water is recycled. Tailings (left-over earth) containing copper oxide are routed to leaching tanks or are returned to the surrounding terrain. Once copper has been concentrated, it can be turned into pure copper cathode in two different methods:

In order to identify the effect of the potassium cyanide (KCN) concentration on the metal recovery percentage for gold, silver and copper, a third experimental test was carried out. The results of this test showed that the highest percentage of gold recovery corresponds to the lowest concentration of KCN (0.06 g 1 -1 ) used in the test ( Fig. 10 ).
