Flotation, nke a makwaara dị ka froth flotation, bụ usoro nhazi ịnweta nke na-ekewa mineral bara uru na mineral gangue na gas-mmiri siri ike interface site n'ịkwalite ọdịiche dị na ọdịdị elu nke mineral dị iche iche. A na-akpọkwa ya “nkewa nke ihu.” Usoro ọ bụla ozugbo ma ọ bụ na-apụtaghị ìhè utilizes frasi interfaces ikewapụ mineral ahụ dabere na iche na ha interfacial Njirimara na-akpọ flotation.
Mineral elu Njirimara na-ezo aka anụ ahụ na chemical e ji mara nke ịnweta urughuru na-ebupụta, dị ka elu wettability, elu eletriki Njirimara, ụdị nke chemical agbụ n'elu atọm, saturation, na reactivity. Ihe dị iche iche ịnweta mineral na-egosipụta ihe dị iche iche dị n'elu, na site n'iji ihe dị iche iche eme ihe site n'enyemaka nke akụkụ akụkụ, enwere ike nweta nkewa nke ịnweta na ịba ụba. Ya mere, usoro flotation gụnyere mmekọrịta nke gas, mmiri mmiri, na akụkụ siri ike na interface.
Enwere ike ịgbanwe ihe ndị dị n'elu ala site na ntinye aka aka iji mee ka ọdịiche dị n'etiti mineral bara uru na mineral gangue, si otú ahụ na-eme ka nkewa ha dị mfe. Na flotation, flotation reagents na-ejikarị eme ka artificially gbanwee ịnweta elu Njirimara, welie ọdịiche dị n'etiti mineral, na-abawanye ma ọ bụ ibelata hydrophobicity nke ịnweta elu.
