Crushing Methods and thier Classification – Mineral Processing

Feb 14, 2021· Crushing process. Crushing is the process of breaking down large solid material, such as pieces of ore or coal, in order to reduce their size to a specified one, to ensure a certain granulometric composition of fractions. As a result of crushing, the mineral grains open up to a given degree.

Mineral processing - Wikipedia

Mineral processing can involve four general types of unit operation: comminution – particle size reduction; sizing – separation of particle sizes by screening or classification; concentration by taking advantage of physical and surface chemical properties; and dewatering – solid/liquid separation. In all of these processes, the most important considerations are the economics of the processes, which is dictated by the grade and recovery of the final product. To do this, the mineralogy of the ore needs to be considered as this dictates the amount of liberation required and the processes that can occur. The smalle…

Trends in the Crushing of Mineral Ores - Mineral Processing

Crushing is an important step in the complex process of mineral processing (Fig. 1). In open pit mines, rock chunks with edge lengths of 2 m have to be processed. In underground mines, the biggest chunk sizes are about 0.5 m. Crushers have the task of reducing the ore rock to particle sizes in the millimetre range for subsequent grinding.

Metallurgic Processes | Boundless Chemistry

The grade or concentration of an ore mineral, or metal, as well as its form of occurrence, will directly affect the costs associated with mining it. The cost of extraction must be weighed against the metal value contained in the rock to determine which ores should be processed and which ores are of too low a grade to be worth mining.
