Abstract

The invention discloses a technical method for producing high-quality feldspar from tantalum-niobium ore tailings. The technical method comprises the following steps: removing strong magnetic iron from tailings by performing weak magnetic separation, and then utilizing strong magnetic separation to remove weak magnetic iron, thereby obtaining a high-quality feldspar product. For an accompanying resource, namely, feldspar, in the tantalum-niobium ore, a combined technology of successively performing weak magnetic separation and strong magnetic separation for efficiently removing impurities from the tailings after recycling tantalum, niobium and lepidolite, thereby obtaining the high-quality feldspar product. The technical method has the characteristics of simple process, high environmental benefit, good economic benefit, and the like.

Description

technical field [0001] The invention relates to a process method for producing high-quality feldspar from tailings of tantalum-niobium ore. Background technique [0002] Feldspar is an aluminosilicate rock mineral of potassium, sodium, calcium, barium and other alkali metals and alkaline earth metals, and its main component is SiO 2 、A1 2 o 3 、K 2 O, Na 2 O, CaO, and MgO are important rock-forming minerals, which are mainly used in the glass and ceramic industries, and others are used in chemicals, abrasives, glass fibers, welding electrodes, enamel, and fillers. With the vigorous development of the world economy; promote the development of enterprise products to high-level products. High-end products require high-grade raw materials. Although many domestic mines have rich feldspar reserves, their quality is poor, and they can only be supplied to ceramic factories as blanks. The economic benefits of mining are low, and feldspar products have limited uses. The future d...
