Abstract
The invention discloses a simple measuring method for the content of micro-fine-particle-level particles. The simple measuring method includes the following steps that 1, a simple liquid separating device is manufactured through a beaker, a test tube stand, a flexible rubber hose and a clamp in a laboratory; 2, settling time required when different particles settle by a fixed height is determined; 3, when the settling time is up, liquid above a settling starting point of the fixed height is pumped out through a siphon; the process is carried out at least twice till the settling range is a fresh water layer, then the collected liquid is filtered, dried and weighed, and the content of the micro-fine-particle-level particles in tailings is calculated. According to the simple measuring method, measuring and calculation are carried out through the common tools in the laboratory, the simple measuring method is simple and easy to operate, inconvenience caused when measuring is carried out through a laser particle size analyzer is avoided, and therefore a department without a special instrument can measure the content of the micro-fine-particle-level particles and learn production conditions in time.
