到目前为止，铜湿法冶金主要以处理低品位矿石为主。堆浸（heap leaching)是低品位氧化铜矿的最重要浸取方法，通常是指用专门开采的矿石筑堆进行浸取的作业，堆浸有一套严格的作业程序。而对开拓矿山等过程产生的废矿石进行浸取，一般称作废石堆浸（dump leaching)，它的作业程序要简单、粗放得多。不过，有的学者把含有黄铜矿，浸取周期很长的矿石堆浸，也称为dump leaching。 So far, copper wet metallurgy mainly deals with low grade ores. Heap leaching, heap leaching) is the most important leaching of low grade copper oxide method, usually refers to using the special mining of ore heap leaching of operations, heap leaching has a set of strict working procedures. In the case of the mining and mining, the waste ore is generally referred to as the dump leaching, and its operating procedure is simple and extensive. However, some scholars have included the yellow copper deposit, which is a long soak of ore, called the dump leaching. 筑堆前的预备试脸 Prepare the face before building a pile 　　为了正确掌握堆浸的技术和经济指标，在实施堆浸工程前需进行充分的浸取化学和工程的试验，通常包括：矿石的矿物组成、成分、化学和物理性质测定，如总铜和酸溶铜的品位、可浸取性、渗透性、浸出速度、耗酸量等。需要确定的堆浸主要参数有矿石的粒度、喷淋浸取液速度及堆高。试验的方法主要有柱浸和试验堆浸出。但在进行柱浸之前还要做一些预备试验。 In order to correctly grasp the technical and economic indicators of heap leaching, the need to fully before implementation of the project of heap leaching the leaching of chemical and engineering test, usually includes: the ore mineral composition, composition, determination of chemical and physical properties, such as the grade of copper and acid soluble copper, can leach, permeability and leaching speed, acid consumption, etc. The main parameters of the heap leaching need to be determined are the grain size of the ore, the velocity of the spray extract and the heap height. The method of experiment mainly has the leaching and test heap leaching. But there are some preliminary tests to be done before the column is soaked.
