The dry type magnetic separator is commonly used iron ore and manganese ore beneficiation equipment. It is the mainstream strong magnet separator‚ which is specialized in processing dry magnetic minerals. The wet type magnetic separator use liquid diluents to improve separation efficiency. The dry type magnetic separator requires that the material must be dry‚ and can move freely between the particles. Or it will affect the separation result‚ and even cannot separate materials.

Metals Iraj Malik 12/10/2012 MYP-5 The International School A metal is defined as a chemical element that is malleable and ductile‚ usually solid‚ has a characteristic luster‚ and is a good conductor of heat and electricity‚ e.g. copper or iron. Metals form oxides that are basic‚ they are good reducing agents and metals have lower electro negatives.There are many properties of metals. The chemical properties are that they can combine together with other metals to form am alloy. The mechanical
