浙江平阳矾矿的蕴藏量丰富,目前该地所采用的冶炼方法依然沿用数百年前的土法,收回率非常之低,仅及理论收回率的40%上下。在政府大力号召增产节约的今天,我们应该考虑如何克服这种不合理现象。在目前当地的工业条件下,要想大规模地机械化起来,还是有困难的。但在土法的基础上逐步加以改进,不论在技术方面、或设备方面,却是很可能而且极其必要。下列图表充分地说明了该地现行炼矾的损失概况,表里所指数字,仅是一厂一日的损失情况,如把许多厂和全年的损失累积起来,这数字就显得格外可怕。为了响应增产节约的号召,我们特别要计较这些问题,靠技 Zhejiang Pingyang alum mine is rich in reserves, the smelting method currently used here is still used hundreds of years ago native law, the recovery rate is very low, only 40% of the theoretical recovery rate from top to bottom. Today, when the government calls for more production and more economy, we should consider how to overcome this unreasonable phenomenon. Under the present local industrial conditions, it is still difficult to mass-mechanize it. However, it is quite possible and necessary to gradually improve on the basis of indigenous law both in terms of technology and equipment. The following chart fully illustrates the loss profile of the existing smelters in the area. The figures in the table and in the table are only one day's losses of a factory. This figure is especially frightening if we sum up the losses of many factories and the whole year. In response to the call for increased production and saving, we particularly need to consider these issues and rely on technology
