Mineral processing or mineral beneficiation or upgradation involves handling of three primary types of ROM ore material which has been blasted, fragmented and brought out from in situ position. These materials can be used directly or by simple or complex processing and even applying extractive metallurgy like hydrometallurgical or pyrometallurgical methods.
Two main types are indicated. The first type where the rolls are rotated in opposite direction with one roll spring loaded. Here, the mineral particles are nipped and crushed as they pass between rolls. In the second type, known as high pressure grinding roll (HPGR), the mineral sizes are reduced by compressive and interparticle pressure.

Level measurements for extreme process conditions can easily be done with the help of radiometric measurement technology. Invented by Berthold, this technology has been providing reliable measurements for more than 70 years. Gamma radiation from an externally mounted source penetrates the vessel and is attenuated by product level inside the vessel.
The 19 th International Powder & Bulk Solids Processing Conference & Exhibition (IPB 2020) was successfully held at the Shanghai World Expo Exhibition & Convention Center on 29 th to 31 st July, 2020. In this exhibition, nearly 200 exhibitors in the fields of crushing, grinding, screening, drying, mixing, filtering, conveying, packaging, testing,

Level Measurement Contactless level measurement for industrial applications invented by Berthold . In the process industry, precise systems for level and level switch measurement are fundamental and make an important contribution to the safety and high quality of production and logistics processes.
Mineral Processing Decreasing ore grades and depleting mineral reserves are no longer the only drivers behind the need to develop new technologies to process ore. Sustainable mining technologies provide economic, social and environmental benefits over the long term, overcoming negative impacts to land, air, water and local communities.
Increased gold recovery higher dissolved oxygen level in leaching process enhances the gold cyanidation, thus increasing gold extraction rate significantly. Decreased retention time by leaching conventional leaching time of 96/72 hrs can be reduced by up to 50 %. Increased ore throughput
