Extraction of copper from copper slag: Mineralogical

高达10%返现 Feb 07, 2015 Copper slag was subjected to in-depth mineralogical characterization by integrated instrumental techniques and evaluated for the efficacy of physical beneficiation and mixed meso-acidophilic bioleaching tests towards recovery of copper. Point-to-point mineral chemistry of the copper slag is discussed in detail to give better insight into the association of copper in slag.

RECOVERY OF COPPER FROM COPPER SLAG AND COPPER

Copper extraction from the slag was typically found to be twice as high as that from the slag flotation tailings. Hydrogen peroxide was determined to be the best lixiviant. Thus, copper and iron extractions were 63.4% and 48.6%, respectively, when leaching the slag with 3 M H 2 O 2

Jun 15, 2020 1. Introduction. Copper is an indispensable basic raw material for modern industry, however, the grade of copper ore is relatively low in China for the reason that the copper mines are dominated by lean ore, associated ore, and symbiotic ore, especially in the process of smelting it is necessary to add fluxes such as calcium oxide and silica, thus producing a large amount of copper
