Potential environmental pollution from copper metallurgy

Jun 01, 2021 Copper occurs in nature in the form of sulphide and oxide ores, salt minerals and as native copper. It is the second most used non-ferrous metal in industry (Boulamanti and Moya, 2016).According to the United States Geological Survey (USGS), the 2019 global annual copper extraction was about 20 million tons ().The highest annual mining capacity was recorded in Chile (5.6

Copper production & environmental impact

Copper history • Copper’s earliest use is recorded in Anatolia in around 7250 BC in the form of coins and decorations. Evidence of copper smelting has been found in Serbia from around 5000 BC though it is thought that smelting occurred in a variety of locations in Asia and Europe at about the same time.

Jan 01, 2012 The flotation of nickel sulphide minerals is normally difficult in the presence of serpentine minerals due to the coating of serpentine particles on the nickel mineral surface. To improve the flotation, dispersants such as polyphosphate and carboxy methyl cellulose are normally used to remove the slime coating. However, in the flotation using high ionic strength process water, these

The Critical Role of Pulp Density on Flotation Separation

In nickel-copper sulfide ore processing, serpentine is a common gangue mineral encountered in complex sulfide ores and can easily cause entrainment during flotation [].Large amounts of serpentine in the flotation concentrate reduces the effectiveness of smelting, often resulting in the imposition of smelter penalties on mineral processing companies [].

Effect of a novel phosphate on the flotation of serpentine

May 01, 2020 In the flotation process of serpentine-containing copper-nickel sulfide ore, serpentine slime coatings significantly reduced the flotation performance of copper-nickel sulfide. Sodium phytate is a highly effective dispersant for MgO control in the flotation of copper-nickel ore.

The Critical Role of Pulp Density on Flotation Separation

A nickel-copper sulfide system usually coexists with serpentine in deposits. Low nickel-copper recovery and high content of serpentine in concentration adversely affects subsequent metallurgical processes. In this study, test data showed different rheological results at various densities. When the solid ratio of sulfide to serpentine was 1:1, lower pulp density (20 wt %) contributed to better
