Problems solved by technology

[0003] my country's feldspar resources are very rich, mainly potassium feldspar, but there are few high-quality feldspar mines that can meet industrial requirements, and most of them contain quartz, muscovite, biotite, rutile, magnetite, hematite, Limonite, some feldspar raw ores also contain apatite, pyrite, titanite, hornblende, tourmaline, etc., the iron content is relatively high, and the whiteness of feldspar or fired whiteness cannot meet the requirements

Embodiment 1

[0030] For the pegmatite low-grade feldspar ore in a certain place in Hunan, the above-mentioned process was used for beneficiation and removal of impurities. See the experimental procedure figure 1 . The whiteness of the feldspar raw ore is about 25 when it is directly fired. After the new process of flotation to remove impurities, the number of flotation stages is 10 times. figure 1 , the whiteness of the final direct burning of the concentrate can reach more than 59, and the yield is about 70%. The results are shown in Table 1. It can be seen from the results that the final removal rate of impurities such as titanium and iron can reach 95.5% by adopting the combination agent system of the present invention, and the effect is more obvious.

Embodiment 2

[0034] Aiming at the pegmatite granite low-grade potassium albite ore in a certain place in Jiangxi, the above-mentioned process was used for beneficiation and removal of impurities. For the experimental process and the times and amounts of reagents added during the flotation process, please refer to figure 2. The feldspar raw ore is directly fired with a whiteness of about 11. After the new process of flotation to remove impurities, the number of flotation stages is 12, and the concentrated ore is directly fired with a whiteness of more than 50, and the yield is about 65%. The results are shown in the table. 2. It can be seen from the results that the final removal rate of impurities such as titanium and iron can reach 93.4% by using the combination agent system described in the present invention, and the effect is better.

Abstract

The invention relates to an efficient ore dressing and impurity removal process for potassium and sodium feldspar ores which are complex and difficult to process and a combined medicament thereof. The process comprises the following steps of: desliming and regulating the pH value of ore pulp to 8 to 10 in the phases of desliming by ore washing and grading by ore grinding; adding 1,000 to 2,000 g/t of saponification oleic acid and 1,000 to 2,000 g/t of benzohydroxamic acid in the alkaline flotation phase of reverse flotation impurity removal to perform collection and floatation on iron and titanium minerals by anions, wherein in the saponification oleic acid, a mass ratio of the oleic acid to sodium carbonate is 1:(0.3-0.5); and after dehydrating, regulating the pH value of the ore pulp to2 to 3 in the acidic floatation phase, adding 800 to 1,500 g/t of sodium chloride and 800 to 1,500 g/t of potassium chloride to inhibit potassium and sodium feldspar, and adding 200 to 400 g/t of dodecanaminium and 200 to 400 g/t of methyl isobutyl carbinol (MIBC) which serve as emulsified cation collecting agents to perform the floatation impurities with colors. By the process, feldspar concentrates in which the content of Fe2O3 and TiO2 is below 0.1 percent, and the content of Na2O and K2O is over 14 percent can be obtained, and the whiteness of the directly-sintered feldspar concentrates can reach over 55, so the feldspar concentrates can be used as super high-quality ceramic raw materials, and other products can be used for firing bricks. In addition, return water used in the process in the moisture phase is recycled, namely water dehydrated after alkaline flotation and return water of acidic tailings can return to the process to be recycled, so the process is high in comprehensive recovery efficiency, economic, practical, energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to a high-efficiency beneficiation and impurity removal process for complex and refractory potassium albite feldspar ores and a combined agent used, belonging to the field of comprehensive utilization of resources. Background technique [0002] Feldspar is a potassium, sodium and calcium aluminum silicate mineral with a frame structure composed of silicon-oxygen tetrahedrons. Feldspar has a melting point between 1100 and 1300 ° C and good chemical stability. It can be used together with quartz and aluminosilicate It has the characteristics of fluxing effect during melting, and is often used in the manufacture of glass and as a fluxing agent for ceramic blank glaze, and can reduce the firing temperature. In the enamel raw material industry, feldspar can be matched with other mineral raw materials. In addition, feldspar can also be used in abrasive tools and abrasives in the abrasive industry; in the production of glass fibers; as ...
