Popis:	Flowsheet improvements, such as series/parallel SX plant configurations, discontinuation of plant sumps and improved filter pumping concepts, the use of in-settler baffle systems, and the Krebs and combined mixer-settler designs offer oportunities to reduce SX plant cost. Today’s plants employ permanent cathodes and mechanical stripping, and the increased capital cost can be offset by labor savings and higher current densities. The wider use of HDPE and new cell construction materials also reduce capital cost. The “Portelex” type of relocatable design embodies such new, cost-saving measures in a simple basic plant. Organic inventory and losses are reduced by new, fast-settling, hybrid organic reagents with improved kinetics and selectivity.
