Field Proven Metals Displacement Chromatography (MDC) reduces Unit Recovery Costs for Metals in Mining Applications with Clean Technology
Chela Tech, Inc. has announced that all rights for separating metals from solutions using United States Patent Number 6,946,070 for Composite Matrices with Interstitial Polymer Networks is assigned to Chela Tech, Inc. This invention relates in general to the preparation and use of matrices having solid spaces, interstitial spaces and interstitial polymer networks. In particular, the interstitial polymer networks have utility in chemical and biochemical separations, solid phase synthesis, catalysis of chemical reactions, and immobilized enzyme reactors.
This invention enables Chela Tech, Inc. to commercialize nano-fishing nets for metals that enable very high flow rates and selective capture. This invention is embodied in metals displacement chromatography (MDC) columns for separations of metals from solutions for mining, environmental, and other applications.
The first product is an automated gold recovery skid to be delivered Summer 2006 to selected test sites to show high flow rate, fast loading and stripping, high selectivity, and long life for recovery and concentration of cyanide-gold-cyanide complex from pregnant solutions.
According to Dr. Richard Hammen, CTO: "Our technology in the form of metal displacement chromatography (MDC) columns has been successfully field tested and currently can capture Ag; Al; As; Au; CrO4=; Cu; Ga; Hg; Mn; Ni; Pb; Pt; UO2=; and Zn to non-detectible levels for discard solutions, or to desired economic cut-off levels. And we can develop metals recovery for other metals in a one to three month time framework. MDC costs per unit metal are essentially the same at any dilution factor."
Bo Varga, VP Marketing explains: "Our revenue focus in 2006 is on gold recovery. We want to rapidly build a business of major value to the global mining industry. We expect to license our technology for environmental and other applications."
