Digitalization Solutions in the Mineral Processing Industry:
The technologies used in mineral process engineering are evolving. The digital mineral processing solutions are based on advances in our ability to instrumentally measure phenomena at several stages of the beneficiation circuit, manage the data in real-time, and to analyze these data using machine learning to develop the next generation 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.Advanced Analytics for Mineral Processing SpringerLink

Materials Free Full-Text Optimization of the SAG Grinding Process
Considering the continuous increase in production costs and resource optimization, more than a strategic objective has become imperative in the copper mining industry. In the search to improve the efficiency in the use of resources, the present work develops models of a semi-autogenous grinding (SAG) mill using statistical analysis and A mineral processing plant in this study consists of a comminution and a separation circuit. The comminution circuit’s operational performance primarily depends on the mill’s performance. Since grindcurves define the operational performance range of a mill, the grindcurves are used to define the setpoints for the economic controlledBenefits of process control systems in mineral processing

Mineral processing is the process in which chemical or physical methods are used to separate the useful minerals in the ore from the useless minerals (usually called gangue) or hazardous minerals, or to separate multiple useful minerals. In the early years, mineral processing was called mineral concentration or mineral engineering in China.The horizontal IsaMills are generally used as a regrinding mill to liberate the finely dispersed mineral of economic interest. The feed is usually the cyclone overflow from conventional grinding circuits such as a ball mill circuit. The grinding media fed with the mineral slurry occupies 70–80% of the internal volume of the mill.Stirred Mills Ultrafine Grinding ScienceDirect
