SEPLITE® LSC719 is gold-selective resin with a T-butylamine functional group. In the Cyanidation leach or acid chloride leach solutions, selective anion exchange resins has been recognized as more cost efficient method than other alternative routes like activated carbon to extract the gold. The resin has a very strong mechanical stability and large particle size, specially designed for systems with fixed or fluidized beds and Resin-In-Pulp (RIP) processing.
