Abstract	Thickeners of different manufacturers were compared when designing the flowsheet for thickening tailings of gravity concentration of the Vasilievsky mine ore. As a result, high-rate Supaflo thickener of 15 m in diameter was installed at the gold recovery plant. The thickener demonstrated reliable continuous operation with the plant capacity of 300 th tpy. The study conducted in 2006 with the current ore demonstrated the possibility of using the same thickener with the plant production increase up to 1 mln tpy in terms of ore but with higher flocculant consumption, with Praestol 2520 being an optimum flocculant and ensuring the necessary underflow density and overflow purity.

Title	Southern african ion exchange plant for nickel recovery
Author	Wijnberg B.
Author`s data	Wijnberg B., SepTor, Outotec (Netherlands), e-mail: ben.wijnberg@outotec.com
Abstract	Outotec has installed a SepTor continuous counter-current carousel ion exchange system at a copper mine situated in South Africa. The copper from the smelter is cast into anodes which are then transported to the refinery for electrolysis. Nickel is accumulated in the electrowinning circuit. A bleed stream is taken from the electrowinning cells, and passed through a separate set of cells where copper in the bleed stream is completely plated out, leaving only nickel and other dissolved impurities. Then the stream with 10–15 gpl of nickel content is passed through a SepTor continuous counter current ion exchange system. The SepTor system takes the nickel from the solution and increases its concentration to 70–80 gpl, due to the highly efficient counter-current elution.
Keywords	SepTor system, distribution valve, nickel recovery, resin static capacitance, process kinetics, elution.

Title	Generation slurry particle size analysers
Authors	Kongas M., Saloheimo K.
Authors` data	Kongas M., Saloheimo K., matti.kongas@outotec.com, Outotec Minerals Oy
Abstract	New technology for on-line particle size analysis of mineral slurries has opened up new applications for particle size measurement. In some cases the particle size distribution of the final concentrate is an important quality issue. This article discusses established on-line particle size analysis technologies and presents experiences on the use of a new technique employing laser diffraction in several minerals processing operations. The main features of the new size analyser are a simple dilution system and multiple scattering correction algorithm, which allows wide solids content variations of diluted sample in the measurement cell. The following applications are discussed: Blaine number measurement of Fe concentrate before pelletizing, grinding of variable batches of ore and paste thickener Control.
Keywords	Flotation, grinding, particle size analysis, ultrasonic measurement, laser diffraction, on-stream Analyser.
