Problem with gold recovery from sulphide ore How may a mill get the maximum recovery of gold from a sulphide ore at the least capital cost and at the same time obtain the highest net return This latter point is most important In many cases a gold mill using an allcyanide flowsheet with fine grinding of all the ore will report very low gold content in the tailings particularly on an

microbubble mediated flotation process In WO2007068446 conventionally done by dissolved air flotation with high power usage but is done with the potential for low power dissipation 4

Oxidic ore can be concentrated using flotation or if it has a low acid demand it may be economic to acid heap leach the stockpile is the most importan t part of the flotation process

In the coarsest fraction above 150 µm exposure of copper sulphides is low with most particles having the lowest sulphide exposure 10 where recovery via the existing flotation circuit is poorest at only 30 This presents a significant opportunity for the application of HydroFloatTM

Silvia Serranti Giuseppe Bonifazi in Use of Recycled Plastics in Ecoefficient Concrete 2019 244 Flotation Flotation processes are based on the different surface wettability properties of materials Wang et al 2015In principle flotation works very similarly to a sink and float process where the density characteristics of the materials with respect to that of the medium where they

The process is particularly suited to treatment of eutrophic stored lowland or otherwise algae laden waters and soft low alkalinity upland coloured waters Longhurst 1987 Rees 1979 Like all clarification processes flotation performance depends on the effectiveness of coagulation and flocculation

In the mining industry flotation is a process that concentrates minerals from their ores prior to metal recovery Current practice uses slurry pHs in excess of 10 achieved by adding burnt lime CaO However lime production is an energyintensive process that releases large quantities of carbon dioxide into the atmosphere
