Embodiment Construction

[0020] A method for purifying and whitening weathered feldspar provided by the invention is characterized in that it comprises the following steps,

[0021] a. The feldspar raw ore is crushed, ore-grinded, and deslimed step by step to remove the muddy cement to obtain feldspar concentrate with a suitable particle size. The particle size of the feldspar concentrate is 40 mesh ≤ D50 ≤ 400 mesh. The particle size requirement of feldspar sand or feldspar powder used in the ceramic industry is met, and the various processes of crushing, grinding and desliming all adopt the existing technology.

[0022] b. Carry out n-stage gravity separation treatment on the deslimed ore to remove dark heavy minerals such as rutile, zircon, hornblende or garnet in the feldspar concentrate. The number of stages of gravity separation is 1≤n≤5, which is preferred in the present invention for 2 segments,

[0023] c. The re-selected feldspar concentrate is subjected to medium-intensity magnetic separat...

Abstract

The invention relates to a purifying and whitening method for weathered feldspar. The purifying and whitening method is characterized by including the following steps of a, carrying out smashing, ore grinding and desliming on raw ore of the feldspar section by section, removing argillaceous cement to obtain feldspar concentrate with appropriate granularity, wherein the granularity meets the granularity requirement of feldspar sand or feldspar powder for the ceramic industry; b, carrying out n-section gravity separation on the ore subjected to desliming and removing dark-colored heavy mineral of rutile, zirconite, hornblende or garnet in the feldspar concentrate; c, carrying out medium-intensity magnetic separation on the feldspar concentrate subjected to gravity separation, and removing mechanical iron in the ore grinding process and partial ferromagnetic iron-containing dark-colored mineral; and d, carrying out m-section high-intensity magnetic separation on the feldspar concentrate. The purifying and whitening method has the advantages that the technology is simple, the cost is low, pollution is avoided, no chemical substances are added in the beneficiation process, the environment is protected, available resources are fully utilized, ceramic is saved, the crisis that the resources are exhausted day by day is alleviated, industrial production is convenient, and the whiteness of raw ore powder of the feldspar is improved.

Description

technical field [0001] The invention relates to the technical field of mineral processing and purification, in particular to a method for purifying and whitening weathered feldspar. Background technique [0002] Flotation is a means to use different collectors to interact with the mineral surface according to the different properties of the mineral surface, and finally use the buoyancy of foam to remove it. Quartz is the main component of glass raw materials, and its particle size composition is strictly controlled. Under the glass particle size, most of the quartz particles are not dissociated as monomers, but are associated with impurity minerals or exist in the form of inclusions. All surface properties Relatively close, and the specific gravity of the particles is relatively large, which greatly increases the difficulty of flotation. [0003] Due to different ore-forming conditions, the composition of impurity minerals contained in quartz, but because the flotation reag...
