Tenders are invited for Fabrication and supply of CALM IX based Mixer-Settler
12 shows a schematic representation of a mixer-settler
for mixing the two solutions and then separating them to be sent to the other layer.
Tenova TAKRAF will provide an agglomeration plant, an on-off leach pad measuring 3,000 m by 800 m and a waste handling system; Tenova Bateman Technologies will supply the SX plant, which will use Bateman's proprietary reverse-flow mixer-settler
The lab features a bespoke 30-stage mini-centrifugal contactor cascade and an 18-stage small-scale mixer-settler
battery to allow for solvent extraction-based actinide separations.
One way to implement separations utilizing the process is to use a common mixer-settler
Quinn Process Equipment will display its expanded line of pilot plant and small commercial size SX Mixer-Settler
With respect to R&D, Kvaerner's non-ferrous group considers it a minor part of its strategy, with some historical work in the area of mixer-settler
technology and reverse flow technology.
A pilot-scale version of the VSF mixer-settler
design was tested at Codelco's Chuquicamata mine in 1992 before the commercial version was installed at Zaldivar in 1995.
It has a conventional 2 x 1 SX circuit configuration and incorporates a novel, cost-effective reverse flow mixer-settler
The washing efficiency of the wash mixer-settler
is also important because of RT's high chloride content.
The SX mixer-settler
will recover 90% of the copper from the pregnant liquor, the remaining 10% of the copper will be returned to the heap leach in the raffinate with the addition of sulphuric acid.
The development of more selective extractants and improved mixer-settler
designs have reduced the size and therefore the capital costs of modern SX/EW plants.
