1、内蒙古牛庆沟手摇盘尾矿试验。用450×1000毫米摇床对该尾矿进行选别,其结果为原金矿品位9.96克/吨,处理量730公斤,回收金量7.2克,尾矿金品位0.1克/吨。 2.转经召重砂试验。试样为手摇盘尾矿(420公斤)与精吹尾矿(20公斤)。试验流程为混汞筒-混汞溜槽流程。试验结果为原矿金品位98克/吨,海棉金量57.2克,纯金量41.8克,尾矿金品位3克/吨。 3、精吹尾矿试验。均采用混汞溜槽回收细粒金。
1, Niuqinggou hand pallet tailings test. The tailings were sorted by 450 × 1000 mm shaker. The result was 9.96 g / t for original gold ore, 730 kg for treatment, 7.2 g for recovered gold and 0.1 g / t for gold tailings. 2. Transfer summoned sand test. Samples for the hand crank tailings (420 kg) and fine blow tailings (20 kg). The test procedure is amalgamation cylinder - amalgamation chute flow. The test results for the raw ore gold grade 98 grams / ton, sponge gold volume 57.2 grams, 41.8 grams of pure gold, gold tailings grade 3 g / ton. 3, refined tailings test. Mercury amalgam tank are used to recover fine grain gold.
