Silver mine tailings ultra-fine activated fine powder and preparation technology thereof

Abstract

The invention discloses silver mine tailings ultra-fine activated fine powder and a preparation technology thereof. According to the present invention, the technical route comprising crushing screening, washing and impurity removing, component adjusting, mixing drying, ultra-fine grinding, vortex powder separation and other operation units is set, the special and originally-designed technical equipment such as a vibrating type water flow washing impurity removing machine and a cage type rotor vortex ultra-fine powder separator is used, and silver mine tailings are adopted as a raw material to produce the silver mine tailings ultra-fine activated fine powder, wherein the outstanding characteristics of complete system, advanced and mature technology, high production efficiency, good operation quality and the like are provided; the produced silver mine tailings ultra-fine activated fine powder can be used for the large-scale replacement of the cement clinker to produce the high-performance cement products, can further be used as the fine material so as to be directly used for mixing the high-strength concrete, and can further be used as the high-quality building decoration product main raw material; and the multiple benefits such as solid waste resource utilization, environmental pollution control, energy source consumption reducing, material variety increasing, and the like can be achieved.

Description

technical field [0001] This patent relates to a treatment and utilization technology of industrial solid waste, in particular to a superfine activated micropowder of silver ore tailings and its preparation technology. Background technique [0002] Mine tailings are the waste slag remaining after multiple rounds of screening such as primary selection, re-selection, and selection in the metal ore beneficiation process. It is a very important industrial solid waste. At present, the vast majority of metal ores in my country adopt wet beneficiation, and most of the tailings are discharged in a fluid state, and are stored and managed by building tailings dams. Storage and management of tailings not only requires a large amount of land, but also requires a huge investment in the construction of a dam body, which is responsible for daily monitoring, maintenance, and overhaul. After long-term storage and drying of mine tailings, part of the tailings will form tailings powder. This k...
