An example of copper ore enrichment in the Lubin Region will be the base of discussing of the raw material approach. Copper ore, apart from the main useful components, i e copper, silver and gold, ycontains several accompanying elements (cadmium, arsenic, lead and others). The author will present an analysis of possibilities and profitability of

Introduction to Mineral Processing. Mineral processing is a field that contends with procedures and technologies used for separating valuable minerals from gangue or waste rock. It is a process that converts the extracted ore through mining activity into a more concentrated material, which serves as an input for the extractive metallurgy.
