Minerals Free Full-Text Study of Copper Leaching
Mining activity produces a series of wastes that must be treated to avoid environmental pollution. In addition, some of these mining wastes still contain metallic elements that are interesting for their cessing and extractive metallurgy. Section 2 addresses the general problem of applying ML in mining and metallurgical processes. In Section 3, the analysis is focused on mineral processing and extractive metallurgy. Finally, in Section 4, some conclusions are pre‐ sented. 2.Article On the Challenges of Applying Machine Learning in Mineral

Water Free Full-Text Environmental Impact Assessment of Mine
The generation of tailings in the world today is immense, since only ounces or pounds of metals are extracted for each ton of ore processed. In 2022, it was estimated that more than 14 billion metric tons of mining tailings were produced per year in the world. Currently, many environmental problems associated with tailings management in both The majority of the current mining operations in Chile are processing copper sulfide minerals, where copper concentrates are obtained by the froth flotation process. This process requires considerable water input to obtain copper concentrate, and the water quality is a relevant factor in achieving high enrichment of valuable minerals Minerals Free Full-Text Using Waste Brine from Desalination
