:: Sumitomo Metal Mining Chromium Recovery Pilot Plant


Sumitomo Metal Mining Co., Ltd. (SMM) has decided to construct a pilot plant to recover chromium from nickel ore through Coral Bay Nickel Corporation (CBNC), its majority owned subsidiary located on Palawan Island in the Philippines, and commence operations from September 2013.

Using HPAL technology, SMM produces nickel-cobalt mixed sulfides through CBNC. The raw material for this process is nickel ore, which contains iron, chromium, and other valuable metals as well as nickel and cobalt. However, only nickel and cobalt are currently recovered and the remaining material is disposed of in landfills. Through research and development aimed at recovering these valuable metals, SMM has established technology for the separation and recovery of chromium from nickel ore as chromite.

Based on this technology, SMM is currently in the process of constructing a pilot plant for the recovery of chromite at CBNC, and shall commence operations from September 2013. The planned annual production volume of chromite at the pilot plant is approximately 10,000 tons.

Through its majority owned subsidiary Taganito HPAL Nickel Corporation (THPAL) located in Makati City in the Philippines, SMM plans to commence operations in fall 2013 at a second plant on Mindanao Island producing nickel-cobalt mixed sulfides using HPAL technology. Based on the operational results of the CBNC pilot plant, SMM is planning to construct a commercial-scale chromite recovery plant at THPAL. SMM shall henceforth continue to make efforts towards the efficient recovery of valuable metals.
