Maritime Resources Corp. (TSXV:MAE) reported a recovery of 96% of the contained gold using a coarse grind and conventional bulk sulphide flotation process during test work on samples of core from its Orion gold deposit near Springdale, Newfoundland.
As quoted in the press release:
The core samples for the flotation testwork were ground to 82.0% to 99.7% passing 74 microns followed by open circuit batch rougher flotation tests with a conventional flotation reagent scheme and reagent dosage. A rougher stage gold recovery of 96.1% with a concentrate grade of 45.2 g/t gold was achieved for Sample A, and a recovery of 95.9% with a concentrate grade of 66.1 g/t gold was achieved for Sample B. The flotation kinetics for all tests indicated that the gold floated quite quickly for both samples, with over 90% recovery within the first three minutes and the fastest rates being observed with a coarser grind. No attempt was made to optimize the grind or flotation reagents in this stage of metallurgical testwork but will be included in future test programs.
Eric Norton, President and CEO of Maritime, comments:
We are very pleased with the results of the Orion pre-concentration testwork. Being able to achieve a 96% recovery of gold, while reducing the overall tonnes of material to be transported or requiring further treatment to only 5% of the original mass, opens up a number of options for the potential development of the Orion deposit. The Company could produce a concentrate on site that would be suitable for sale to a smelter, toll treat the concentrate through a local mill, or build a small processing plant on site to produce Dore metal ourselves. The coarse grind and fast flotation kinetics would indicate that the sizing of equipment for an on-site plant would be very small.
