First, the production of a variety of tin products program put forward (A) the nature of the mine I process the second section of the natural deposition and artificial accumulation of sand 钖 mine re-election plant. Ore stone in the main recovery of minerals, associated metal minerals are limonite, hematite, manganese nodules, lead oxide, followed by a small amount of natural copper and zinc oxide. Gangue is quartz, calcite, feldspar, mica, tourmaline and a lot of clay. Ore 钖 grade 0.303%, 1.7% lead grade. The ore has the following characteristics. 1, the fine grain size of ore containing high. In the ore
