Copper Sulfur Grinding

Home Copper Sulfur Grinding

The remaining mixture is a molten copper sulfide referred to as matte. The next step in the refining process is to oxidize liquid matte in order to remove iron to burn off sulfide content as sulfur dioxide. The result is 97-99%, blister copper. The term blister copper comes from the bubbles produced by sulfur dioxide on the surface of the copper.

The copper ore bodies mined from 1911 to 1938 at Kennecott, Alaska (now within the Wrangell–St. Elias National Park and Preserve), are examples of potentially environmentally "friendly" ore deposits. The ore bodies consisted of veins of massive chalcocite (a mineral consisting of copper and sulfur).

Copper Alloys: Most brasses, bronzes, and copper are stained when exposed to cutting oils containing active sulfur and chlorine; thus, sulfurized and sulfochlorinated oils should not be used. For most operations a straight soluble oil, mixed to 1 part oil and 20 to 25 parts water is satisfactory.


Mechanochemical sulfidization of a mixed sulfide/oxide copper ore by co-grinding with sulfur and additives including Mg(NO 3) 2 and Fe(NO 3) 3 salts and iron, aluminum and magnesium powders was investigated for the first time. Also, the influence of sulfidization during the wet-milling process was examined on the separation efficiency and recovery of copper in detail.

Copper is an essential trace element that is included in some over-the-counter multivitamin and mineral supplements, even though copper deficiency is quite rare and supplementation is rarely needed. The amounts of copper found in typical supplements has not been associated with serum enzyme elevations or with clinically apparent liver injury. However, accidental or intentional copper overdose ...


In this study, the mechanism which underpins the different interactions of chalcopyrite, a primary copper sulfide mineral, and chalcocite, a secondary copper sulfide mineral, with bentonite, a clay mineral, during the grinding with stainless steel media was investigated by a range of techniques including XPS (X-ray Photoelectron Spectroscopy) analysis, electrokinetic studies and Cryo-SEM ...


Classification: Copper and copper alloys are considered an "article" and are not hazardous in its solid form. However, certain processes such as cutting, milling, grinding, melting and welding could result in some serious hazardous materials being emitted. The GHS classification below pertains to these emitted products during these processes.


Copper Smelting Process. In the autogenous system described by this report, sulfide concentrate and silica flux are blown into the furnace through a specially designed burner with oxygen and is flash smelted to about 50-percent copper matte. The matte flows down an inclined crucible, countercurrent to the slag flow, to the converting zone at ...


Copper concentrate is the first commercial product of the copper production line and is composed of approximately equal parts of copper, iron and sulfide. Concentrates are the raw material for all copper smelters, which by processing it obtain an impure form of metallic copper, anode or blister copper, which is later used to produce high purity ...


Copper ores containing chalcopyrite can be concentrated to produce a concentrate with between 20% and 30% copper-in-concentrate (usually 27–29% copper); the remainder of the concentrate is iron and sulfur in the chalcopyrite, and unwanted impurities such as silicate gangue minerals or other sulfide minerals, typically minor amounts of pyrite ...


Refining copper results in three and a half times as much waste as the amount of copper produced. This waste is not only in the form of solids that must be disposed of or recycled, but also sulfur dioxide gas. Sulfur dioxide is a significant air pollutant, particularly notable as …


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 bronze—an alloy that allowed stronger weapons and tools. Brass, an alloy of …

Most current copper extraction processes burn sulfide minerals in air, which produces sulfur dioxide, a harmful air pollutant that has to be captured and reprocessed, but the new method produces elemental sulfur, which can be safely reused, for example, in fertilizers. The researchers also used electrolysis to produce rhenium and molybdenum ...


The content of copper and sulfide in the disseminated copper-sulfide ore is low, the copper-sulfide ratio is relatively large, and the ore generally contains 10%-40% pyrite. The gangue is unevenly infiltrated with copper minerals and pyrite, and some pyrites closely co-exist with copper minerals, and the aggregates have large particle sizes.


Pure copper is rarely found in nature, but is usually combined with other chemicals in the form of copper ores. There are about 15 copper ores mined commercially in 40 countries around the world. The most common are known as sulfide ores in which the copper is chemically bonded with sulfur.
