堆浸底板,集液沟和溶液池都要求不透不漏,故在堆浸作业中,高质量的地膜衬料大为有用。用于堆浸作业的地膜可使溶浸液的损失减至最少。高密度聚乙烯(HDPE)地膜衬料特别能耐稀碱性或酸性水溶液的腐蚀和不渗漏。将0.1毫米厚的HDPE地膜与0.6米厚的天然
Heap immersion floor, sump and solution pool are required impermeable, so in heap leaching operations, high-quality film lining is very useful. Membranes used for heap leaching can minimize the loss of infusions. High-density polyethylene (HDPE) film lining particularly resistant to dilute alkaline or acidic aqueous solution of corrosion and leakage. 0.1 mm thick HDPE mulch and 0.6 m thick natural
