本文用数学方法模拟实验室闭路试验,目的是用开路试验指标来预测闭路时的理论指标。实验室闭路流程试验是使用不连续的试验设备来模拟闭路流程,其做法是按照开路试验选定的流程和作业条件,接连而重复地做若干次试验。每一次所得中间产品给到下一相应作业中。直至试验物料基本上达到平衡为止。 In this paper, mathematical closed-circuit laboratory simulation test, the purpose is to use the open circuit test to predict the theoretical indicators when closed. Laboratory closed-circuit test is the use of non-continuous test equipment to simulate the closed-circuit process, the practice is in accordance with the open-circuit test selected processes and operating conditions, a series of repeated tests to do a few. Each time the resulting intermediate product is given to the next corresponding operation. Until the test material basically reached equilibrium.
