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.
Tenders are invited for Fabrication and supply of CALM IX based Mixer-Settler
It has a conventional 2 x 1 SX circuit configuration and incorporates a novel, cost-effective reverse flow mixer-settler
The most important operating criteria for an SX plant are its operating capacity and the stage efficiency of specific mixer-settlers
. 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.
