A milling enriched technics for celestine ore

Abstract

The invention relates to a beneficiation concentration process for celestite. The invention is characterized in that celestite ore is sent into a scrubbing desliming equipment to perform the desliming after being crushed to be smaller than 6 mm, the scrubbing desliming concentration is 40 to 50 percent, the obtained ore slime is sent into an ore slime pond to be stored, the obtained product after the desliming is delivered into a grinding system to be ground, the grinding concentration is 60 to 70 percent, to lead composite mineral to achieve the dissociation of a fundamental monomer, products in a roughing cell are flotation tailings to be discharged and stacked, the reflotation is performed to roughing froth products for three times, a reflotation froth product is also flotation concentrate for the last time, and the flotation concentrate is the finished product of the flotation concentrate after being concentrated, filtered, and dried; the products in a reflotation cell for each time of middlings are merged and singly treated. The flow is simple, the invention is easy to be realized, the operation and the controlling are easy, the product quality is high, the recovery ratio of the celestite is high, and the invention can be widely applied to the medium and low grade celestite concentration production.

Description

technical field [0001] The invention relates to a beneficiation process, in particular to a beneficiation and enrichment process suitable for carbonate-type celestite ore with middle and low grade mud-containing and salt-containing fine particles. Background technique [0002] Strontium is widely used in various fields such as electronics, chemical industry, metallurgy, military industry, light industry, medicine and optics because of its strong X-ray absorption function and unique physical and chemical properties. With the continuous development of world industry, the field of use of strontium is gradually expanding and changing. Strontium is known as "metal monosodium glutamate". Strontium ore resources are not only important strategic mineral resources in the world, but their status and role in my country's national economy will also increase and become more and more important. Strontium is a rare metal mineral resource. There are few strontium resources in the world. On...

Problems solved by technology

The Qinghai Provincial Central Laboratory of the Ministry of Geology and Mineral Resources and the Northwest Research Institute of Mining and Metallurgy of Baiyin have carried out a small laboratory test of the conventional gravity separation process and flotation process on the Dafengshan Celestite Mine. low problem

The Chinese patent application with the publication number CN1765519 discloses a desliming-flotation celestite concentrate process, which has the following defects: 1. desliming after rod milling, desliming feed is too fine, desliming efficiency is not high, ore The mud grade is relatively high; ②The flotation process is complex, the number of beneficiation is more than five times, and multiple middle ore returns cause the flotation process to deteriorate, the flotation speed is reduced, and the recovery rate is reduced; ③The flotation index is unstable and the operation control is difficult. The reason is that after fine grinding, the quality of lapis lazuli is small and the surface energy is large, so the influence on mineral flotation behavior is quite complicated, and the requirements for flotation equipment conditions, flotation reagent conditions and flotation process operation control are quite high, reaching a severe level; ④ Not Recycling of mineral processing backwater
