An electrolytic manganese pilot plant having a daily capacity of 2,000 lb. (900 kg.) has been operated by the Bureau of Mines for the past 5 years. The results recorded are on the effect of certain variables on the electrodeposition of manganese, namely, electrode spacing, rate of feed to the cells, manganese concentration in the cell catholyte, and length of cell operation before cleaning. It was found that in the catholyte outflow the manganese concentration should be maintained at an average of 12 g./L. A decrease or increase of manganese content results in lowered efficiency through scaling and cracking of the deposits. The optimum manganese concentration in the feed was found to be 32 g./L, representing 20 g./L Mn removed from the solution. A greater removal of manganese and, consequently, a lower manganese feed rate increases the catholyte pH, which in turn decreases the current efficiency. When all factors, such as oxide formation at the anode, calcium sulfate precipitation on the diaphragms, and precipitation of manganese hydroxide in the catholyte, are taken into consideration, the cells should be cleaned every seven weeks to obtain most efficient cell operation. There is an increase of about 0.2 volt/cell between the first and seventh week of operation.
在过去的5年里，矿务局一直在运营一家电解锰中试工厂，该工厂的日生产能力为2000磅(900公斤)。记录的结果是关于某些变量对锰电沉积的影响，即电极间距、进给电池的速度、电池阴极液中的锰浓度以及清洗前电池操作的时间。结果表明，阴极液流出液中锰的浓度应保持在平均12 g /L。锰含量的减少或增加会通过结垢和开裂导致效率降低。饲料中锰的最佳浓度为32 g /L，即溶液中锰的去除率为20 g /L。更大的锰去除率，因此，更低的锰进料速率增加了阴极电解质的pH值，这反过来降低了电流效率。当考虑到所有因素，如阳极的氧化物形成、隔膜上的硫酸钙沉淀和阴极液中氢氧化锰的沉淀时，应每七周清洗一次电池，以获得最有效的电池运行。在操作的第一周和第七周之间，每电池增加约0.2伏。
