New Flotation Lab Circuit Will Cut Test Turnaround Time

Eriez Flotation Division (EFD) has commissioned a fully automated, four-stage lab-scale column circuit for flotation testing on sulfide and industrial minerals. Operating parameters such as air flow rate, wash water flow rate, reagent addition rates and pH level are regulated using a programmable logic controller (PLC). The flotation circuit can be altered to accommodate multiple circuit configurations ranging from one (i.e. rougher) to four (i.e. rougher-scavenger-cleaner-cleaner) unit operations, dependent upon the characteristics of the feed ore. The circuit is also capable of incorporating recirculating loads. The automated circuit can be utilized to conduct steady-state column flotation tests at feed rates of up to 15 kg/h.

Metso to Increase Screening Media Production Capacity

Metso is expanding its global manufacturing capacity for rubber screening media used in minerals processing by investing in three new injection presses. The presses will be installed at Metso’s facilities in Australia, India and Sweden by early 2018.

The company said the EUR 1.7-million investment will significantly increase its global rubber screening media manufacturing capacity. Demand for its screening media has grown in the mining segment after the introduction of 1 x 1-ft (305- x 305-millimeter) modular screening media, Trellex 305PS, in 2016, according to Metso.
