Core to present critical new information on its patented Toowong Process at the ALTA 2017 conference in Perth.
Core will be presenting critical new information on its patented Toowong Process at the ALTA 2017 conference in Perth next week. The paper is titled, “The economics of removing arsenic from copper concentrates using the Toowong Process.”
The paper reflects a large amount of work completed by Core, with partners Mineral Technologies and Whittle Consulting, developing detailed costings for the Toowong Process, along with investigating the impact of the Process on the overall project value. This will allow prospective projects to evaluate the economic impact of including the Toowong Process in their design. The paper will demonstrate that removing arsenic at the mine site instead of paying penalties at the smelter can have a large positive impact on the economics of the mining project.
A unique technology for the removal of arsenic, antimony and other deleterious elements from base metal concentrates, the Toowong Process selectively leaches these elements at the mine-site, leaving the metals of value in the concentrate as a premium clean product. The process was developed in 2010-2012 by Core Resources. A $4.5 M pilot plant in 2012 successfully reduced arsenic grades from 1.1% + in the feed to <0.1% arsenic in the final product, treating three concentrate samples from around the world.
For mining operations, the value of using the Toowong Process lies not simply in a treatment process for the removal of arsenic, but in its potential to enable a re-optimisation of the mining schedule without the constraint of planning around deleterious elements.
