Crushing in Mineral Processing
In mineral processing or metallurgy, the first stage of comminution is crushing. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear-resistant plate/surface. Less abrasive and softer rocks or stones

Without any doubt the mineralogy is the key aspect of the process performance. Basically, there are several options to be considered at the moment of evaluate the ore. The first alternative is a gravimetry process and
Mineral Processing an overview ScienceDirect Topics
Mineral processing, mineral beneficiation, or upgradation involves handling three primary types of ROM material, which have been blasted, fragmented, and brought out from an in situ position. These materials can be used directly or by simple or complex processing and even by applying extractive metallurgy like hydrometallurgical or pyrometallurgical methods.

Roasting (metallurgy) Wikipedia
Roasting is a process of heating of sulphide ore to a high temperature in presence of air. It is a step of the processing of certain ores.More specifically, roasting is a metallurgical process involving gas–solid reactions at elevated temperatures with the goal of purifying the metal component(s). Often before roasting, the ore has already been partially purified, e.g. by froth flotation.
3 Technologies in Exploration, Mining, and Processing
Mineral and coal processing encompasses unit processes required to size, separate, and process minerals for eventual use. Unit processes include comminution (crushing and grinding), sizing (screening or classifying), separation (physical or chemical), dewatering (thickening, filtration, or drying), and hydrometallurgical or stone processing. Pyrometallurgical processing (smelting of mineral
Developments in HPGR technology Mining Magazine
Since HPGRs can process fine ores at moistures of up to 10%, they are used to perform the final stage of grinding. Water is becoming an increasingly scarce resource, and its consumption in mineral-processing plants plays a key role in the development of new mines. The HPGR technology offers several options to reduce the water consumption within
SAQA
Minerals processing is about extracting the valuable minerals contained in the mined ore and producing a saleable product or an enriched concentrate for further processing. It is important to maximise production rate and recovery of the valuable minerals and to minimise the cost of extraction. End products are metals or metal compounds that can be used in a wide variety of applications, e.g.:

The Role of Arsenic in the Mining Industry
Since valuable metals such as copper and gold can also be found in sulfide mineral deposits, mining exploration companies will often look for soil and water with a naturally high arsenic content as a means of locating an ore body. [9] It is, therefore, very important to establish baseline or existing arsenic concentrations in the surrounding environment in order to distinguish between mining
