Beneficial means helpful, advantageous or conferring benefit. Beneficial means something good or advantageous for something.
A beneficiation is the reduction in size of particles of ore before further processing.
Beneficiation
Spiral Concentrators are used in Iron ore beneficiation plants for Gravity Separation. It separates the higher density Iron Ore from Silica based on density difference as concentrate, middling & tailing.

Phosphorus is obtained from phosphate deposits. Phosphate ore beneficiation methods have been continuously enriched in the development. The traditional beneficiation methods include: scrubbing and desliming process, gravity separation, flotation, gravity-magnetic-flotation combined process and roasting process. Scrubbing and desliming process: for ores with a high degree of weathering. Gravity separation: The proportion of main gangue minerals in phosphate rock is similar to that of apatite. In industrial practice, dense medium separation is mainly used. Flotation: Flotation has always been the main method for beneficiation of phosphate ore, especially for complex and difficult ores. Such as positive flotation, single reverse flotation, positive one negative (negative one positive) flotation, double reverse flotation. Roasting method: It is a fairly mature method used in industry to completely remove carbonate from phosphorite ore.
An IDZ is a purpose built industrial estate linked to an international air or sea port, which might contain one or multiple Customs Controlled Areas tailored for manufacturing and storage of goods to boost beneficiation, investment, economic growth and, most importantly, the development of skills and employment.
Such as crushing equipment, grinding equipment, feeding&conveying, screening&washing, and beneficiation equipment.
Saudi Arabia is the largest exporter of oil in the world and it has the largest underground oil reserves. During the reign of the crown prince and current king , Abdullah, a great deal of emphasis has been placed on upstream beneficiation of the oil industry with the result that petrochemicals, fertilisers plastics and polymers are also exported.
