Feb 23, 2016 David Duckworth of consulting company Saint Barbara notes that the issue of high-arsenic (high-As) copper concentrates has been highlighted recently with the start-up of a number of new projects producing this material. Copper concentrates can be divided into clean or complex types, he writes in the companys latest newsletter.

Misplacement of gangue slimes to concentrates also can pose significant concentrate dilution issues as well as requiring much higher flotation residence times to ensure high copper mineral recovery. In a plant where the flotation capacity is fixed, this means lower copper recoveries.
The ship carrying this type of copper concentrate must have on board a Certificate of Fitness for the Carriage of Solid Bulk Cargoes and a Certificate of Fitness for the Carriage of Dangerous Goods listing Metal Sulphide Concentrates, Self-Heating UN 3190 as a permitted cargo and a Cargo Manifest and a Stowage Plan setting forth the location ...
The principal copper ore mineral is chalcopyrite (CuFeS2 ), which is commonly smelted to yield a matte containing 50% copper. In the presence of silica flux, iron is selectively oxidized to a slag. Figure 14 shows a PSD for the CuFeSO system at 1 atm SO 2 as a function of temperature (
Copper concentrates are produced by the beneficiation, or upgrading, of copper ore. A typical copper ore would be 0.7% to 2% copper, a typical copper concentrate would grade around 25% to 35% copper. Copper concentrates are either smelted and refined in-house, or sold to custom smelters.
Today, with a stringent economic and environmental climate prevailing in the copper business, there is increased interest in evaluating new processing alternatives for production. Hydrometallurgical pressure oxidation of copper concentrates is one of the more viable approaches, and several technological candidates have emerged. Of these, an overlooked but, ironically, the first industrially ...
Generally, copper extraction follows the sequence (see Figure below) 1. Beneficiation by froth flotation of ore to give copper concentrate (Optional partial roasting to obtain oxidized material or calcines) 2. Two-stage pyrometallurgical extraction 1. smelting concentrates to matte 2. converting matte by oxidation to crude (converter or ...

Nov 09, 2020 Copper-containing rock, or copper ore, holds only a small percentage of copper. Most of the rock is unwanted material, typically referred to as gangue. There are two main types of copper ore of ...
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 different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different ...

Stage 3 Roasting At this stage of the process, the chemical reactions begin. They convert the copper minerals into copper metal. We can illustrate the types of process using the example of chalcopyrite CuFeS 2.From the formula, it is clear that iron and sulfur have to be removed in order to produce copper.

discovered that heat made copper more malle-able. Casting and smelting of copper began around 4000-3500 B.C. (see figure 6-2). About 2500 B. C., copper was combined with tin to make bronzean alloy that allowed stronger weapons and tools. Brass, an alloy of copper and zinc, probably was not developed until 300 A.D.
Jul 06, 2020 With the gradual decrease in the grade of copper ores being processed, copper concentrates have become more complex with higher impurity and gangue content. This trend has had a detrimental effect on smelters as they have to increase throughput to maintain copper metal production, while increasing operating costs due to processing the increased amounts of secondary products
Alan Taylor, a well-known metallurgical consultant and managing director of ALTA Metallurgical Services, recently commented in his new blog MetBytes about how the industry is looking at ways to handle the problem of impurities in copper concentrates. He wrote Some new players have joined the list of hydromet processes for copper sulphide concentrates.

The Los Pelambres copper mine in Coquimbo region of Chile is currently being expanded in two phases. The mine has been operating since 2000 and currently produces copper concentrates containing gold and silver and a separate molybdenum concentrate. The $1.8bn expansion project, approved in November 2018, is expected to add an average of 60,000t ...

The composition of copper concentrates was assessed for 122 samples, covering the world-wide copper concentrates production (table 1 and 2). Copper concentrates are dominated by copper, iron and sulphur. These elements are incorporated in sulphidic minerals such as chalcopyrite (CuFeS 2), bornite (Cu 5 FeS 4),
Concentrate A has the sulphides being mostly chalcopyrite and some pyrite and a higher gangue fraction. Concentrate B distributes its copper mostly between chalcopyrite and tennantite and has considerably more pyrite. The mercury mineralogy for the two

concentrate. The concentrate may be initially roasted to remove sulphur and moisture. Concentrates are combined with silica sand and limestone and transferred to a furnace to melt them. Melting separates the materials with the heavier copper sinking to the bottom of the furnace, while the
Nov 01, 2016 The payable copper content depends on the grade of copper in the concentrate and is typically 9597% of the contained copper content for concentrates with copper grades between 20 and 30 wt% (Hansen, 2013, Sderstrm, 2008). Treatment and refining charges are imposed to account for costs associated with smelting and refining respectively.
Dec 14, 2020 Meanwhile, Chinese restrictions on the import of Australian copper concentrates has further tightened the short-term supply of raw materials in the domestic market. A recent tender for Chilean clean concentrates was concluded at low-30s, while spot deals concluded between traders and smelters settled at high-40s.
