Get PriceMineral 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
Get PricePost harvest loss is one of the biggest problems affecting economic growth globally. The FAO (Food and Agriculture Organization) estimates that 1/3 rd of loss in the food products occur every year. The loss depends upon the type of crop that is to be cultivated. As the fruits and vegetables are perishable, so their chances are more to get spoiled or degraded
