SANTIAGO, Chile, Sept. 21, 2011 /PRNewswire/ -- White Mountain Titanium Corporation ("White Mountain" or the "Company") (OTC Bulletin Board: WMTM) reports that it has received the final report from SGS Lakefield ("SGS") dealing with processing Cerro Blanco rutile tailings to produce a high grade, sodium feldspar concentrate. This concentrate could find application as a flux and in the glass and ceramics industries.
Utilizing rutile tailings from the previously reported pilot plant test work, SGS examined a number of metallurgical parameters including differential flotation of sodium and potassium feldspars through the use of a variety of flotation collectors and activation modifiers. More than twenty separate flotation tests were carried out to optimise the process flow sheet. Locked cycle tests were then performed and repeated to confirm reproducibility.
Test results established that under optimum conditions a sodium feldspar concentrate assaying 9.96% Na2O and 0.19% Fe2O3 could be produced. Silica and alumina levels were 66.30% SiO2 and 21.00% Al2O3 respectively. Importantly, in all tests iron content in concentrate assayed less than 0.3% Fe2O3. The report recommends further test work which would eventually involve a full scale pilot plant similar to that used to test the Cerro Blanco rutile concentrate process flow sheet.
In other developments, the Company has added four professional engineers to its project team. Reporting to Dr. Antonio Luraschi, Cerro Blanco Project Manager, the additional personnel's responsibilities cover a broad range of activities including permitting and environmental, mine planning and design, process engineering – including electrical and mechanical disciplines, infrastructure and costing.Commenting on these developments, Mike Kurtanjek, the Company's President and CEO, said, "Results from the feldspar test work are very encouraging. Depending on potential customer interest, successful piloting and projected concentrate pricing and costing, the co-production of a sodium feldspar concentrate could make a meaningful, incremental contribution to the project's economics. That said, the economics of the Cerro Blanco final feasibility will be based solely on the production of rutile. Meeting the Company's stated timeline for delivery of rutile concentrate is a top priority, both for our customers and for our shareholders. Out of necessity, further evaluation of the possible co-production of sodium feldspar concentrate from rutile tailings will be undertaken as a separate project with its own budget, milestones and timeline." He went on to say, "Given the strong demand and competition for consulting engineering services, adding in-house engineering expertise further strengthens our ability to meet our production timeline."
