Problems solved by technology

Usually barium-containing carbonate ore is accompanied by other gangue minerals, these associated minerals make the content of barium carbonate in barium-containing carbonate ore low. At present, there are few research reports on beneficiation of barium-containing carbonate ore at home and abroad, and there are occasional reports It is mentioned to process by flotation method, but there are problems such as unsatisfactory concentrate barium carbonate grade and recovery rate

Embodiment 1

[0045] A kind of beneficiation process of barium carbonate ore, its technological process sees figure 1 ; The main mineral composition of the barium-containing carbonate ore that adopts wherein: witherite content is 45.53wt%, barite content is 15.96wt%, waltzite and barite content are all less than 1% (due to content less , the specific value cannot be measured), quartz 17.56%, calcite 7.47%, dolomite 11.82%, pyrite and organic matter are all less than 1% (due to the small content, the specific value cannot be measured); phase analysis shows that the Barium-containing carbonate ores are mainly witherite and barium calcite, and also contain impurity minerals quartz, calcite and a small amount of dolomite and barite; the content of barium carbonate in the raw ore is 56.85% (the barium carbonate in the raw ore comes from Witherite is also derived from the decomposition of other barium-containing minerals such as barite and sentinite), and its beneficiation process includes the fo...

Embodiment 2

[0055] A beneficiation process of barium-containing carbonate ore; the main mineral composition of the barium-containing carbonate ore used in it is: witherite content of 45.53wt%, barium calcite content of 15.96wt%, sendonite and barite The stone content is less than 1% (the specific value cannot be measured due to the small content), quartz 17.56%, calcite 7.47%, dolomite 11.82%, pyrite and organic matter are all less than 1% (due to the small content, it cannot be measured) specific value); phase analysis shows that the barium-containing carbonate ore is mainly based on witherite and barite, and also contains impurity minerals quartz, calcite and a small amount of dolomite and barite; after determination, the ore barium carbonate The content is 56.85% (raw ore barium carbonate is derived from witherite, and also from the decomposition of other barium-containing minerals such as barite and sendonite), and its beneficiation process includes the following steps:

Abstract

The invention discloses a mineral processing process for recycling barium carbonate from baric carbonate ore. The process comprises the steps that firstly, raw ore of the baric carbonate ore is subjected to ore grinding, and fine-sized products are obtained; the obtained fine-sized products are subjected to table grading, and table concentrate, table middlings and table tailings are obtained; then the obtained table middlings and table tailings are mixed, the mixture is grounded again, the obtained ore grinding product is subjected to reverse flotation decarburization in advance, and flotation carbonaceous foam and flotation underflow are obtained; then the flotation underflow and a flotation agent act, direct flotation is carried out, flotation foam and flotation underflow are obtained, and the flotation foam is flotation concentrate; the obtained table concentrate and flotation concentrate are mixed, and barium carbonate concentrate is obtained. According to the process, the high-quality barium carbonate concentrate can be effectively obtained from the barium carbonate containing middle-low grade baric carbonate ore, the baric carbonate ore is effectively recycled, the baric carbonate recycling rate is high, and important economic value and economic significance are achieved.

Description

technical field [0001] The invention relates to the technical field of mineral processing, in particular to a beneficiation process for recovering barium carbonate from barium-containing carbonate ores. Background technique [0002] As a kind of salt minerals, carbonate minerals are mainly distributed in the earth's crust, among which carbonates of calcium and magnesium are the most common, and carbonates of barium are relatively rare. Barium-containing carbonate minerals are mainly toxic heavy stone and barium calcite. [0003] Witherite barium carbonate is a natural carbonate barium ore except barite BaSO 4 Another main barium-containing mineral, the crystals are pseudo-hexagonal bipyramids, and the aggregates are granular, massive, spherical, kidney-shaped, and some are vein-like and fibrous. It is colorless or gray-yellow, glassy luster, hardness 3-4, specific gravity 4.2-4.3, easily soluble in carbonated water and weak acid, and poisonous. Witherite has the character...
