Characteristics of SEPLITE® Gallium recovery resin

 High temp. limit (45+2℃), which reduced the operation risks.

 Good mechanical strength, which dramaticlly reduced the loss of resin.

 Capability and excellent anti-fouling performance.

Cost-effective, main specifications are world leading.


SEPLITE® Indium Recovery Resin

SEPLITE® LXF9 chelating resin is designed with high selectivity under high acidic condition to Indium recovery from the acid preparation supernatant in Zn production. It can realize the enrichment and recovery even in low Indium concentration with simple process and low environmental risks.

SEPLITE® Copper Recovery Resin

SEPLITE® LSC 495 chelating resin is specially designed for Copper adsorption and perfectly used in Copper recovery of mines, mining tailings, electroplating etc, as well as refinery of Copper solutions. It was highly selective to Cu and able to adsorb Copper from strong acidic solutions and not affected by other metal ions. Copper removal rate could be higher than 99%. The capacity exceeds 35g/L.

SEPLITE® Nickel Recovery Resin

The traditional method of Nickel recovery is extraction.Before extraction, pretreatment by precipitating Fe3+ is needed . During the precipitation, around 10% Nickel would enter into the residues and very hard to be recovered. On the other hand saponification of the extractant will consume NaoH. 

SEPLITE® LSC 485 chelating resin has high selectivity to Nikel and not affected by Fe in solution, so no pretreatment was needed which decrease the loss of Ni. Sulfuric acid was used to regenerate LSC 485 so to decrease the alkali consumption. The most important is that selectivity of resins to Ni being over 98%, which significantly decreased Nickel production cost.
