Embodiment 1

[0019] First, choose 20 ore, add water to the dry titanium concentrate, wherein the mass ratio of dry titanium concentrate and water is 60%:40%, and make wet titanium concentrate; secondly, send an appropriate amount of wet titanium concentrate into a ball mill for Wet grinding, wet grinding is divided into two stages, the first stage abrasive is steel ball, the diameter of steel ball is Φ100mm, Φ60mm and Φ40mm respectively, the mass ratio of three types of steel ball is 70%: 15%: 15%, The grinding time of the first stage is 20 minutes; after the first stage is completed, the second stage will be carried out. The abrasive material of the second stage is steel forging, the diameter of the steel forging is 3mm, the length of the steel forging is 4mm, and the grinding time of the second stage is 30min. ;Finally, the wet-milled titanium concentrate and slurry enter the settling tank for sedimentation. After sedimentation and stratification, the upper liquid contains part of the fin...

Abstract

The invention discloses a titanium concentrate pretreatment method and a titanium concentrate palletizing method. The methods aim at solving the problem that the palletizing performance of existing titanium concentrates is poor. By the adoption of the technical scheme, the titanium concentrate pretreatment method includes the steps that firstly, raw materials are prepared; the content of water of selected titanium concentrates is adjusted, the water mass accounts for 20%-40% the total mass of the titanium concentrates and water, and wet titanium concentrates are obtained; wet grinding is conducted, wet grinding is conducted on the wet titanium concentrates through a ball grinding mill, wet grinding is divided into two stages, the grinding material in the first stage is steel balls of three models, the grinding material in the second stage is steel forgings, and finally filtering is conducted; and the wet-ground titanium concentrates and the serous fluid are filtered, and finished fine grain titanium concentrates are obtained. By the adoption of the titanium concentrate pretreatment method, the specific surface area of the titanium concentrates is increased to 50 cm<2> / g to 600 cm<2> / g from 150 cm<2> / g generated before treatment, and the palletizing performance is improved greatly. Bentonite and water are added to the finished fine grain titanium concentrates, palletizing is conducted, the drop strength of manufactured balls ranges from 5 times to 8 times, and the requirement for the quality of the balls in the titanium concentrate palletizing and oxidizing roasting processes can be met.

Description

technical field [0001] The invention relates to a titanium concentrate pretreatment and pelletizing technology, in particular to a pelletizing pretreatment and a titanium concentrate pelletizing method for improving the pelletizing performance of the titanium concentrate. Background technique [0002] In order to improve the comprehensive utilization level of titanium ore resources, Panzhihua Iron and Steel eliminated the traditional gravity separation and magnetic separation processes, and changed them all to flotation to recover titanium resources in Panzhihua vanadium-titanium magnetite. The flagship product of titanium concentrate. According to the particle size level of titanium concentrate, the flotation titanium concentrate products of Panzhihua Iron and Steel Co., Ltd. can be divided into 10 ore and 20 ore. Among them, the particles smaller than 0.074mm in the 10 ore account for about 35%, and the particles smaller than 0.074mm in the 20 ore account for about 60%. I...
