Flotation Process Development in Laboratory

Differential and preferential flotation The pressing problems in differential and preferential flotation of ores are (1) the separation of lead sulphide from zinc sulphide, and (2) the separation of zinc and copper bearing sulphides from sulphides of iron. Methods seeking separation of one sulphide from another by flotation are of two classes, viz.: (1) those in which a difference … Read more

Laboratory Flotation Testing

Batch Laboratory Flotation Testing starts from the 3 fundamental types of flotation processes or methods which can be classed as either: Bulk flotation Differential flotation Sequential flotation While all flotation processes are selective or differential in that one mineral or group of minerals is floated away from accompanying gangue, bulk flotation generally refers to separation … Read more
