The main raw material is copper sulfide ore, and high-grade copper oxide ore can also be smelted in the pyrometallurgical process. The mining grade of copper sulfide is 0.3–2%, and the average mining grade is approximately 0.81%. The mined ore is crushed and pulverized. Then flotation will separate the copper sulfide concentrate.
Introduction. The first report in this recurring series on microbial processes in the minerals industries was published in 2003 (Olson et al. 2003), followed by an update after 10 years (Brierley and Brierley 2013) with bioleaching and biooxidation of sulfide minerals, primarily copper (in the case of bioleaching) and refractory gold ores …
The operating practices in the beneficiation of porphyry copper ores from Chile are reviewed. The factors which affect plant metallurgical results are discussed including: ore mineralogy, reagent scheme and flowsheet. ... water and energy usage, kinetics, and circuit design. A brief introduction of advanced technologies, along with …
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 …

Copper Mining and Macroeconomic Indicators Copper mining has accounted for an average of 10% of Chile's gross domestic product (GDP) for the last two decades. In comparison, the mining industry as a whole represents 10.9% of GDP. Between 1996 and 2016, copper mining as a percentage of economic activity in Chile ranged between …
As the world's largest copper exporter, Chile is encountering a growing number of sulfur-based ore layers containing toxic arsenic in its copper mines. Conven-tional strategies for separating and landfilling arsenic are proving limited in this area. The German-Chilean project team, led on the German side by the Fraunhofer Research …
Smelting and refining all the copper ore in Chile on the one hand helps to reduce global greenhouse gas (GHG) emissions (Sturla et al., 2020), but on the other hand, by concentrating this process in one country (in spite of 12 countries), greatly affects the local population and environment through concentrating the pollutants.
The efficiency of a flotation circuit operation relies on several factors that are pertinent to mineral nature and structure (variability of ore feed, particle size, complex mineralogy, and morphology) as well as the type of instrumentation and operational parameters (design parameters, reagents, quality of process water, air flow rate, and ...
