Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.The primary operations are comminution and concentration, but there are other important operations ...
Mining schedule in inputs sheet – foundation for stockpile calculations. The mining schedule is a summary of the physical aspects of the mining process and is usually provided by the engineers. At its most basic level it should contain (screenshot 1) ore mined (tonne) and the corresponding ore grade (grams/tonne) for each type of ore.

During this phase, the ore is extracted, processed, and refined to produce metal. This section forms the bulk of the focus of the financial model for an operating mine. Once all the ore has been extracted, the mine closure process begins, which can last for several years. The process includes clean-up, reclamation, and environmental monitoring.
Chemicals in the Mining Process. Many different types of chemicals are used throughout the mining process - from naturally occurring acids brought up with ore, to chemicals introduced during processing to break down minerals and control pH levels.
In iron ore design process, according to the ore grade difference, iron ore mining process mapping also have a different character. Follows are the brief introduction of poor iron ore mining process mapping. Before mapping, we should have an investigation about the iron ore mine structure.
The mining process of this foreign iron ore concentrator has a great suitability for the ore. Once iron ore concentration or twice concentration will depend on the type of the ore. When once concentration can get the needed grade, the second concentration groove will be used in the scavenging work to improve the mineral recovery rate.
Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different ...
