Dry grinding of the ore followed by roasting and agitation with cyanide gave a good extraction in a plant treating about 500 tons per day, but the running costs were very high. It was then found that modern flotation methods would enable 90% of the mineral content of the ore to be recovered in a concentrate amounting to less than 10% of the ...

The flotation tests of the Fankou ore were carried out in an XFG flotation machine with a 1.5-L plexiglass cell. For each flotation test, 500 g of Fankou ore and tap water were added into the 1.5-L cell and the pulp was well mixed for several minutes. As required, HCL and NaOH stock solutions were added to adjust the pulp pH to 8.
