Embodiment 1

[0029] The original ore is the Chuanfangyu manganese boronite mine in Jixian County, Tianjin. The manganese boronite mine is a marine sedimentary type. The content of manganese boronite is 54.31%, the content of dolomite is 14.61%, and the content of quartz is 13.37%. stone, chlorite, illite, etc. The main valuable component in the ore is manganese boronite, the molecular formula is Mn 3 B 7 o 13 Cl, mainly semi-euhedral granular particles, mostly produced in the form of aggregates, and the aggregates are coarser in size and loosely combined, with clear contact boundaries with gangue mineral aggregates, and gangue minerals are mainly black-gray microcrystalline dolomite As well as black organic cement, gangue minerals have higher hardness. The chemical diversity analysis and X-ray diffraction analysis were carried out on the raw ore samples of the manganese boronite mine in Jixian County, Tianjin. The results are shown in Table 1. by B 2 o 3 and Cl content calculation an...

[0040] Step 1: Crushing the raw ore until the particle size is less than 2mm, and then sieving into three grades of +0.5mm, -0.5mm ~ +0.15mm, -0.15mm; the crushing adopts the second-stage crushing, and the first stage of the second-stage crushing The jaw crusher is used for crushing, and the long cavity crusher is used for the second stage of crushing.

[0041] Step 2: The -0.5mm~+0.15mm particle grade product obtained in Step 1 is directly thrown as tailings;

[0042] Step 3: Slurry the +0.5mm particle size product obtained in step 1 to obtain pulp 1, scrub and grind the pulp 1, and then sieve to remove the +0.15mm particle size before desliming. get concentrate one;

[0043] In the step 3, the pulp concentration of pulp one is 70%, the scrubbing and grinding equipment is a vertical agitating mill, the stirring speed is 200r / min, the scrubbing time of the agitating mill is 10min, and the filling rate of the agitating mill scrubbing medium is 0%.

Abstract

The invention discloses an enrichment method for chambersite. The method comprises the steps that products of three size fractions of +0.5 mm, -0.5-+0.15 mm and -0.15 mm are crushed and screened; the products of the size fraction of +0.5 mm are scrubbed, ground and subjected to desliming to obtain first concentrate; the products of the size fraction of -0.15 mm are subjected to flotation to obtain second concentrate; and the first concentrate and the second concentrate are mixed to obtain mixed concentrate. The enrichment method for chambersite has the beneficial effects that only the products of the coarse size fraction are scrubbed and ground, so that the amount of grinding is greatly reduced, energy consumption is reduced, and grinding media are not used during the scrubbing and grinding links; the grade of the chambersite is improved to above 90% by screening and primary rough flotation of chambersite concentrate with the chambersite content of about 50%, and the recovery rate is more than 75%; concentration and scavenging are not needed during the flotation link, so that the time is shortened greatly, and the cost is reduced; the method is easy and convenient to operate and popularize.

Description

technical field [0001] The invention relates to the technical field of non-metallic ore beneficiation, in particular to a method for enriching manganese borax ore. Background technique [0002] Manganese boronite is a rare manganese chloroborate. In 1957, manganese boronite mineral was first discovered in the brine recovered from the American oil field. Then R.M.Honea et al. A systematic study was carried out, and in 1962 it was named "Chambersite" after the place of origin. Later, the mineral was found in Mexico, Louisiana, USA and other places. In 2005, it was reported that manganese boronite was found in a sample of rock salt in the Newbrunswick borate deposit in Canada, and it was symbiotic with hydroborite, hydrochlorite, anhydrite, mica minerals, magnesite and quartz. In 1971, my country discovered manganese bororite during the exploration of manganese ore in Dongshui Plant, Jixian County, Tianjin. It is the only manganese bororite deposit found in the world with dev...
