Iron removal is an inevitable step when recycling copper from wastewater. A new process is proposed to enhance iron removal selectively from copper sulfate solution through its chemical precipitation on the surfaces of dolomite (CaMg(CO 3) 2), which is a widely available cheap carbonate mineral.A heterogeneous precipitating reaction of iron ions on the surface of …
Study on Extraction and Separation Performance of Iron …
As the content of iron and aluminum in high-iron bauxite resources do not meet the industrial application requirements of single iron ore and bauxite, the development and utilization must be based on the recovery of iron and aluminum at the same time, and the separation of aluminum and iron is the first step for its comprehensive utilization ...

Separation of silicon and iron in copper slag by …
Approximately 2.0–3.0 t of copper slag (CS) containing 35%–45% iron is generated for every ton of copper produced during the pyrometallurgical process from copper concentrate. Therefore, the recovery of iron from CS utilizes a valuable metal and alleviates the environmental stress caused by stockpile. In this paper, a new method has been developed to realize the …
