PROCESS DESIGN PARIS 23 - 28 APRIL 2018 INTERNATIONAL EXHIBITION FOR CONSTRUCTION AND INFRASTRUCTURE Cobalt bloom visible in first level adit of CSR’s Castle mine near Gowganda, Ontario. Work on lithium, cobalt and graphite processes is a major part of the activity currently at SGS Lakefield in Canada the chute, it was subjected to high rates of wear, causing a reduction in performance. Various designs and options were examined to improve ease of maintenance and thus reduce downtime. “Searching for a design that improved maintainability, we implemented new, modular design upgrades to the chute, so that it could receive maintenance section by section. Thus, when a specific part shows signs of wear, we can disassemble that part and change it quickly. This is also an improvement that was tailored for the client, given that with the original design we had to disassemble the entire equipment to be able to change some parts,” says Alejandro Bravo, Metso Manager of Minerals Process Equipment. Given the success of the project, Minera Doña Inés de Collahuasi SCM is evaluating the implementation of the same upgrade concept in other VPA filters as part of its asset management plan. “With this solution, we have been able to meet some of the availability goals we set for 2017. The filter today works according to the plans drawn up with Metso, which helps us to continue operating efficiently,” says Cristián Barros, Senior Engineer for Symptomatic Process at Collahuasi. BUILDING TOMORROW, TODAY SGS busy with battery minerals at Lakefield Castle Silver Resources Inc recently announced that ongoing underground sampling has returned high-grade cobalt from additional areas on the first level of the Castle mine near Gowganda, Ontario. Areas prospective for cobalt mineralisation were recently highlighted through XRF analysis of the extensive first level workings at Castle. Current sampling is designed to gain a better understanding of the grade intensity and distribution in order to prioritise underground drill targets. Frank Basa, CSR President and CEO, stated: “The cobalt grades we’re encountering underground are extremely encouraging and supports our original thesis that past operators may have left much behind at Castle in their strict focus on mining high-grade silver. At a time when Cobalt prices are at new decade highs, CSR’s access to extensive underground workings at the Castle mine puts the company in a unique position in the northern Ontario cobalt region.” Bulk samples were obtained by removing muck rock from the floor of the drift and chipping out vein material over two lengths of 10 m, each filling a 5 gallon pail with approximately 20 kg of material. A single composite sample was taken by randomly selecting approximately 2 kg from each of the bulk samples. Samples were transported by truck to Swastika Laboratories, an accredited lab, in Swastika, Ontario for assay with analysis by aqua regia digestion and atomic absorption finish.
