A Study on Reduction of Copper Smelting Slag by Carbon …
Copper smelting slag is a solution of molten oxides created during the copper smelting and refining process, and about 1.5 million tons of copper slag is generated annually in Korea. Oxides in copper smelting slag include ferrous (FeO), ferric oxide (Fe 2 O 3), silica (SiO 2 from flux), alumina (AI 2 O 3), calcia (CaO) and magnesia (MgO).

Immobilization of Cd, Zn, and Pb from Soil Treated by …
Decades of mining in South Korea have resulted in the contamination of large amounts of soil by metals. The most feasible approach to site restoration requires the use of a stabilization agent to reduce metal mobility. This study examined the leaching characteristics of limestone used as a stabilization agent when subjected to solutions of differing pH. In a laboratory-scale column test
