Embodiment 1

[0031] refer to figure 1 , a kind of lead-zinc massive ore intelligent sorting method of this implementation, carry out according to the following steps:

[0032] (1) Coarse crushing and primary screening: The lead-zinc raw ore is crushed by a primary crusher and then passed through a double-layer vibrating screen for washing, screening and grading to obtain three particle size grades of +45mm, +12mm ~ -45mm, -12mm ore;

[0033] (2) Secondary crushing: The +45mm ore screened out in step 1) is transported by belt to the secondary crushing crusher, and the crushed ore is transported back to the double-layer vibrating screen in step 1) by belt for washing screen Minute;

[0034] (3) Intelligent sorting and discarding: the +12mm ~ -45mm ore initially screened in step 1) is transported to the X-ray intelligent ore sorting machine through the transport belt for intelligent sorting and discarding, and the X-ray intelligent ore is sorted In the control system of the machine, the se...

Abstract

The invention discloses an intelligent sorting method for lead-zinc massive ore. The method comprises the following steps: (1) coarse crushing and primary screening, specifically, crushing the lead-zinc raw ore by a coarse crushing crusher, and then washing, screening and grading the crushed lead-zinc raw ore by a double-layer vibrating screen; (2) medium crushing, specifically, conveying the primarily screened large-particle-size ore to a medium crushing crusher, and washing and screening the crushed ore through the double-layer vibrating screen in the step (1); (3) intelligent sorting and waste throwing, specifically, conveying the primarily screened medium-particle-size ore to an X-ray intelligent ore sorting machine for intelligently sorting and waste throwing to obtain tailings and waste rocks; and (4) fine crushing and fine screening, specifically, conveying the intelligently sorted fine ore to a fine crushing crusher, and feeding the crushed fine ore into a single-layer vibrating screen for fine screening. According to the intelligent sorting method for the lead-zinc massive ore, the lead-zinc massive ore is coarsely crushed at first, and then the gangue mineral dissociatedin the lead-zinc massive ore is directly thrown out by the X-ray intelligent ore sorting machine, so that the ore dressing cost is reduced, the ore dressing grade and the processing capacity of a dressing plant are improved, the tailing yield is reduced, and the pressure of insufficient storage capacity of a tailing pond is relieved.

Description

technical field [0001] The invention relates to the technical field of copper-zinc mineral processing, in particular to an intelligent sorting method for lead-zinc block ore. Background technique [0002] With the rapid development of China's economy, resource consumption is increasing, which intensifies the tension in the supply of mineral resources. Among them, lead and zinc resources, as important non-ferrous metal mineral resources, play an important role in the national economy and are widely used in electrical appliances. Industry, machinery industry, military industry, metallurgical industry, chemical industry, light industry and pharmaceutical industry and other fields. In addition, lead metal also has many uses in nuclear industry, petroleum industry and other departments; however, lead and zinc resources are scarce resources, and all countries in the world pay attention to and protect lead and zinc as an important strategic resource. [0003] my country is rich in...
