Abstract

The invention discloses a method and a device for preparing tailings nanoparticles by using high-power electromagnetic pulse. The method is to put the crushed tailings into a cavity equipped with a high-power electromagnetic pulse device and use the high-power electromagnetic pulse to pulverize, After crushed tailings are treated at a frequency of 100-300Hz for 10-20min, the frequency increases to 300-500Hz, after 10-20min treatment, the frequency increases to 500-700Hz, and after 10-20min treatment, the frequency increases to 700-900Hz , treated for 10-20min, and finally increased the frequency to 1000-1100Hz, treated for 10-20min, and obtained tailings nanoparticles; the tailings particles obtained after crushing can reach nano-scale, and the energy consumption is small, suitable for all kinds of tailings Mine to prepare nanoparticles.

Description

technical field [0001] The invention relates to a method for preparing nano-particles of tailings by using high-power nanosecond electromagnetic pulses, and belongs to the field of crushing and decomposition of tailings. Background technique [0002] As a country with rich mineral resources, my country has a huge amount of tailings discharge, and tailings have become a key source of environmental pollution. Heavy metals in tailings migrate and transform in various environmental media, and finally focus on the human body, which has a great impact on human health. High risk, possibly life-threatening in severe cases. Therefore, all walks of life urgently need to strengthen the stabilization treatment of tailings. Nowadays, the research on the stabilization treatment of tailings at home and abroad mainly focuses on the microscopic behavior of tailings particles and the migration and transformation mechanism. At the same time, the particle size of tailings It also affects the mi...
