摘　　要：在室内试验研究的基础上 ,在生产现场对贵州某泥质氧化金矿石进行了小堆 (36 5t)、大堆 (10 15t)规模的制粒堆浸工业试验 ,确定了烘干、破碎、造粒、喷淋的相关设备设施以及流程中的主要参数。矿堆渗透性完全满足了浸出的要求 ,浸出率达 90 %以上 ,渣品位低于 0 .2g/t。该工艺简单 ,运行成本低 。Based on the indoor test research, on-site industrial tests were made on granulation-leaching of a Guizhou clayish oxide gold ore, with both small heap (365 t) and large heap (1015 t). The equipment and facilities of drying, crushing, granulation and spraying and the main flowsheet parameters were determined. The heap infiltrability fully met the leaching requirement, and the leaching rate was above 90%, with the residue grade under 0.2 g/t. The technology that is characterized by simple and low cost operation can bring good economic benefit.
