中文摘要:气力浸出槽是金精矿加工过程中氰化法提金的重要设备,槽内矿浆浓度的在线测量对于监控浸出工艺有重要作用。本文介绍了一种基于压差测量原理的在线浓度计,可以在线测量槽内矿浆浓度,还可以监测槽内矿浆浓度的分布情况。该浓度计已成功应用在Φ3.0×12米的国内最大浸出槽上,试验证明该仪器具有测量精度高、可靠性高的特点,解决了浸出槽内浓度在线测量问题。

Development of Pneumatic Leaching Trough Differential Pressure Online Concentration Meter
Abstract:Pneumatic trough is an important equipment in the process of gold concentrate cyaniding, the online measurement of slurry concentration is very important to monitor the leaching process.This paper introduces a kind of on-line concentration measurement based on the principle of differential pressure,it can online measure slurry concentration, and also can monitor the density distribution in trough.The concentration meter has been successfully applied in the largest leaching tank with a diameter of 3 x 12 metres, the test shows that the instrument has the characteristics of high measuring precision, high reliability, and solved the problems of concentration of leaching online measurement .
