The recovery and grade of copper received in the resulting copper concentrate is appreciable and acceptable. Therefore, this study further confirms the Copper–Gold Concentrate Treatment Processes. Based on the chemistry of chalcopyrite dissolution reviewed above, it is now possible to look at different case Case study flowsheets: copper–gold concentrate treatment
Plant copper recovery to copper concentrate and copper concentrate grade are as expected for an ore with low feed grades, but copper recovery is 1. Introduction Conventional treatment of copper–gold concentrates involves smelting, converting, and electrorefining to produce a copper cathode product.

The chapter discusses the flowsheeting based on unit operations and applied to a mineralogical classification of gold ore types. Whether gold is the primary value metal or a part of a suite of metals, such as nickel, cobalt, copper, or platinum-group metals (PGMs), selection of an appropriate combination of these units would likely result in a Figure 1 shows an example of the most common porphyry copper ore type beneficiation flowsheet. Porphyry ores, although generally contain small amount of copper below 1%, belong to easy-to-floatA typical flowsheet used in the flotation process of
Flowsheet 3 looked at the replacement of the ESF with a Slag Concentrator (SC) to improve the overall copper recovery (Fig. 5). Once again, application of a high lance air oxygen enrichment and an intensely cooled furnace configuration were used to improve the energy efficiency of the overall flowsheet, with key characteristics of the Download scientific diagram Proposed NSC enargite concentrate treatment flowsheet. from publication: Hydrometallurgical Processing of Gold-Bearing Copper Enargite Concentrates This paperProposed NSC enargite concentrate treatment flowsheet.

The fluorite is a major process implication, because fluorine is a penalty element in saleable copper concentrate. Grades of F in saleable concentrate exceeding 300 ppm attract penalties at the point of sale, for example at the OK Tedi operation, where the fluorine grades range from 400 to 1500 ppm (Lauder et al., 2003).Brewer, R.E., 2004, “Copper concentrate pressure leaching — Plant scale-up from continuous lab testing,” Minerals 2007, “Sulfate-based flowsheet options for hydrometallurgical treatment of copper sulfide concentrates,” Proceedings of the Sixth Download citation.

Copper sulfide minerals are the predominant raw materials for copper metal (Hawker et al., 2018), while copper oxide minerals have also provided the important resources for copper supplies (Li etFlowsheet selection issues are discussed under the following headings. 4.2. Treatment of high-copper ores. Adams (1999) has proposed a classification of gold–copper ores according to the relative concentrations of the two metals. Ores with high copper values are invariably exploited via flotation and smelting with gold recovered in a refinery.Process flowsheet selection ScienceDirect
The final copper concentrate produced contains 25.1% copper with 86% recovery. The Mikheevskii MPE, producing 18 million t of porphyry copper ore per year (at a grade of 0.4% cop-per), applies the bulk-differential flowsheet and pro-duces copper and molybdenum concentrates.

Penalties can significantly reduce the value of copper concentrate. For instance, in this paper, the fluorine penalty deduction ranges from $7 to $54 for copper concentrate containing 0.1 to 0.57% fluorine ion, accounting for 0.3 to 2.4% of the net value of the concentrate before the penalty element deduction.Copper Content in Ores and Concentrates. A global copper mine-by-mine review undertaken by ICSG found that the global average copper ore grade was as low as 0.45% copper in reported reserves and only 0.65% copper in 2015 copper mine production. Global weighted average of copper concentrate output in a large sample of plants was Processing of Complex Materials in the Copper Industry:
