一、概况芒特艾萨矿石的重要矿物特征是方铅矿、闪锌矿、银黝铜矿、黄铁矿和少量的伴生硫化矿以明显的整合条带体赋存于整个Urquhart页岩中,成为一个厚约1100米的薄层状黄铁矿页岩、白云石页岩,火山页岩的岩层。矿石粒度在-50毫米时开始解离为富硫化矿颗粒和以脉石为主的颗粒,而在-18毫米变得更为明 I. Overview The major mineral characteristics of Mount Isa are galena, sphalerite, silver-tetrahedrite, pyrite, and a few associated sulfide ores occurring in the entire Urquhart Shale with distinctly integrated bands , A thin layer of pyrite shale about 1,100 meters thick, dolomite shale, volcanic shale rock formation. Ore size starts to dissociate to sulfide-rich ore particles and gangue-dominated particles at -50 mm and becomes clearer at -18 mm
