求翻译：未使用絮凝剂之前，齐大山铁矿新建的3台Ф53m浓密机的溢流浊度一直很高，有时高达100000ppm。在试验研究及现场初步试验的基础上，确认絮凝剂KP07对浓密机的使用状况改善明显，因此决定进行系统的工业试验研究，试验目的主要在于确定考查药剂的特性、使用成本及通过添加药剂所带来的经济效益。工业试验的主要内容有：冬季低温考查药剂性能试验、磁选尾矿满负荷考查试验、综合尾矿考查试验、高浓度输送试验是什么意思？

Not before using the flocculant, 3 §æ 53m of qidashan iron ore mine new thickener overflow turbidity has been very high, sometimes as high as 100000ppm. Experimental study and field preliminary tests on the basis of confirming flocculant of KP07 for thickener usage improved significantly, therefore
