Key words: copper, roasting,oksidation,fluidized bed,mechanism 1. INTRODUCTION In copper production, starting raw materials are sulphide ores and copper concentrates. One of the most significant processes in the treatment of starting raw material is roasting in fluidized layer, since its success affects the succeeding calcine roasting phase

How to Concentrate Copper -

 · The fluids appear to be the most primitive and copper-rich ore fluids identified to date . The entire assemblage of immiscible fluids—silicate melt, hydrothermal liquid, and hydrothermal vapor—provides a snapshot of a highly productive magmatic-hydrothermal transition. Perhaps more importantly, the assemblage highlights a geological process that

Copper Processing PowerPoint - Oresome Resources

Find out how copper ore is extracted and turned into copper metal. This is a PowerPoint presentation showing the properties, uses and extraction of copper. It includes details of the mining and processing of copper ore as well as smelting, converting and refining to produce copper metal. Most slides contain photographs or labelled diagrams. Teacher's []

Zinc: smelting, producing and classification-Metalpedia

Typically, a zinc concentrate contains about 55% of zinc with some copper, lead and iron. Zinc concentration is usually done at the mine site to keep transport costs to smelters as low as possible. Zinc smelting. Zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc.

Whitepaper - Automated analysis of copper concentrates

The need for analysing copper concentrates to determine the copper content accurately and rapidly is increasing. Hence, there exists a demand for automated systems that perform the wet chemistry methods for the analysis of copper concentration in powder samples. Automation brings the advantage of increased hands-off capacity and improving accuracy and precision
