C4 is a high-arsenic concentrate which would not be accepted in some countries, and whose preferred destination would presumably be commodity traders who would blend it with cleaner concentrates. Finally, C5 is a high-copper concentrate with high values of punishable elements which may only be treated by specialized smelters.

Often in powder form, copper concentrate is purchased by copper smelters to use in the production of copper anode and blister copper, the next saleable copper product in the value-added chain.

In theory, this surplus will support higher copper treatment and refining charges in the years to come. Final word. Base metal smelters assess a myriad of charges and deductions to ensure the value of their operations. Base treatment charges form the bulk of that value and are the primary focus of contract negotiations.

The first commercial copper product, in an increasing chain of added value, is the copper concentrate, which main components are copper, iron and sulfide. During the same …

In some cases, the concentrate is submitted to an additional processing step to extract a by-product (e.g. molybdenum sulfide). Finally, the copper concentrate is dried ready for transportation to the next step (smelting). The copper concentrate production process does not involve any chemical modification of the original ore body. 2.

This document sets out the basic methods for sampling copper, lead, zinc and nickel concentrates from moving streams and stationary lots, including stopped-belt sampling, to provide samples for chemical analysis, physical testing and determination of moisture content, in accordance with the relevant International Standards.

The purpose of smelting is to enrich most of the copper in the copper concentrate in the matte phase. The gangue, oxides and impurity elements were combined in the slag phase to completely separate the copper matte in the slag phase. In this paper, a mathematical model based on the optimization of copper concentrate cost and the content of impurity elements in …
