Lindian Resources Limited announced that it has received results of the Digestion test work on the screened ores from the Bouba Plateau within the Gaoual High Grade Conglomerate Bauxite Project in Guinea. A total of 28 tests were completed upon the coarse fraction bauxite ore samples, representing 4 samples from each of the 7 test pits sampled. Each sampled was digested at both low temperature and high temperature equivalents by Bureau Veritas ­ Perth with Total Available Alumina and Reactive Silica reported. A summary of the results is as below: The Low Temperature Digestions of the high grade test pits bauxite averaged 88% TAA recovery (51.2% TAA) and 59% RSi recovery (1.6% RSi). The High Temperature Digestions of the HG test pits bauxite averaged 93% TAA recovery (54.4% TAA) and 92% RSi recovery (2.6% RSi). The lower of recoveries in TAA in the LT Digestions of the HG pits bauxite ore is caused by a minor component of Boehmite. This is determined by the HT digestions having a smaller range of TAA recoveries and are those TAA recoveries themselves being very high (>90% TAA). The increasing RSi recovery from LT to HT digestions for the HG test pits indicates that there is only a small presence of coarse unreactive quartz, and quartz that is present may be very fine grained and able to be digested at the HT digestions. The LG test pits indicated that all of the coarse fraction bauxite samples were able to be digested easily with LT TAA recoveries ranging from 85-87% recovery (averaging 86%), and the HT TAA recoveries ranging from 88-90% recovery (averaging 89%). The digestion test work completed upon the beneficiated ores has confirmed that these ores are gibbsite dominant and suited well to both LT and HT Bayer process alumina plants. With the much-reduced silica levels in the beneficiated ores, the RSi grades have now been decreased to levels in line with the quality bauxites being mined and exported from Guinea.
