The benefits of Copper-containing sewage sludge

The benefits of Copper-containing sewage sludge What is sewage sludge? Sewage sludge is the solid residue that remains after municipal and industrial wastewaters have been treated in sewage treatment plants. What is sewage sludge currently used for? Sewage sludge is managed in primarily 3 ways: land application, dumping and incineration.

CN104726700B - The method producing copper concentrate

The present invention relates to a kind of method that copper-contained sludge produces copper concentrate, carry out with condition by following processing step successively: being interrupted acid adding, the pH value controlling whole course of reaction solution is about 2.5, reacts about 100min, obtain stirring acidleach slurry;To stirring acidleach slurry sodium sulfide solution, stir .

Recycling of galvanic copper sludge for pure copper

recovered from the galvanic copper sludge up to 92%, with the highest current efficiency of 99.45% when using 2 M leached solution at 2.2 V. However, to obtain the highest copper purity of 99.92%, the electrowinning condition would be 1 M leached solutions at 2.2 V are shown in Table 6. The recovered copper could, therefore, be used

Mining Waste | Special Wastes | Wastes | US EPA

Mining wastes include waste generated during the extraction, beneficiation, and processing of minerals. Most extraction and beneficiation wastes from hardrock mining (the mining of metallic ores and phosphate rock) and 20 specific mineral processing wastes (see side bar below) are categorized by EPA as "special wastes" and have been exempted by .

Chapter 6 Copper Production Technology

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 copper and zinc, probably was not developed until 300 A.D.

Copper Removal at the Gardner Wastewater Treatment

activated sludge tanks. The results show that dissolved copper is less of a problem and harder to filter than total copper, so total copper is the primary target for removal in the WWTF. The results from this experiment can be found below in Figure 1. Figure 1: Average total & dissolved copper …

Characterization of Precious Metal Resources in Copper

 · Studies have been carried out on precious metal association, on a typical Indian copper slag sample using SEM–EDS. The studies revealed the presence of platinum as well as gold, reported here for the first time, in the copper metal as well as different types of metallic sulphides phases of the copper slag. These phases are either entrapped in the silicate minerals or are present as free .

Removal of copper from aqueous solutions using biosolids

 · Abstract. The effect of pH, biosolid dosage, initial copper concentration, and contact time on copper removal from aqueous solutions using biosolids (waste sludge cake) was investigated through batch experiments. The copper removal increased by time and initial metal concentrations. The equilibrium time was achieved for copper ion after 35 min.

tons of copper ore to recover 441,000 metric tons of copper. Hydrometallurgical Processing The leaching process extracts copper by dissolution in sulfuric acid. This method is suitable for low-grade copper ore bodies for which customary mining operations would be uneconomical, as well as for the leaching of remnant ores from abandon mines.
