The invention provides a flotation method of zinc oxide ore. The method comprises the steps that in the pretreatment process of flotation, the zinc oxide ore is crushed and levigated firstly, and the slurry concentration is adjusted to range from 15wt% to 20wt%; a scattering agent and a gangue mineral inhibitor are added in sequence, and then a flocculating agent is added for selective flocculation; then pregelatinized starch is added, the mixture is evenly stirred, and then sulfuric acid is added to adjust the pH value of slurry to 1-5; and a collecting agent and a foaming agent are added after stirring is carried out at a low speed for 2-5 minutes, and zinc concentrate is obtained through flotation according to a conventional process. Through addition of the pregelatinized starch, stability of selective floccules is enhanced, then the sulfuric acid is added so that tight absorption between smithsonite and carbon dioxide microbubbles generated through a reaction can be achieved, and then zinc minerals-floccules are recovered through conventional flotation, so that the beneficiation index of the ore is increased, and consumption of the collecting agent and the foaming agent can be effectively reduced.

The invention discloses an ore separation method for the reverse flotation of smithsonite from sulphide lead-zinc flotation tailings. According to the ore separation method, tailings obtained after the flotation of lead sulphide and zinc sulphide from high-garnet-type lead-zinc sulphide are fed. The ore separation method comprises the following steps: step 1, carrying out strong magnetic separation on the fed tailings by adopting a high-gradient pulsating strong magnetic separation machine, so as to obtain strong magnetic separation concentrate and strong magnetic separation tailings; step 2,carrying out flotation on the strong magnetic separation tailings by adopting a flotation machine, so as to obtain flotation concentrate and flotation tailings; and step 3, carrying out wet screeningand classification on the flotation concentrate to obtain materials in two different size fractions, and carrying out separation on the materials in two different size fractions again, so as to obtainconcentrates in two size fractions and tailings in two size fractions. By adoption of the ore separation method, the smithsonite can be separated from the fed tailings. Besides, the agent consumptionis low, the enrichment effect is good, and the recovery rate is relatively ideal.

The invention discloses zinc-containing compound fertilizer for wheat. The zinc-containing compound fertilizer is prepared from raw materials in parts by weight as follows: 25-27 parts of zinc nitrate, 16-18 parts of smithsonite, 28-30 parts of urea, 13-15 parts of ammoniated superphosphate, 24-26 parts of potassium chloride, 20-22 parts of soybean straw, 5-7 parts of vermiculite, 3-5 parts of cycad leaves, 8-10 parts of bark of a white bark pine, 5-7 parts of calocedrus macrolepis leaves, 12-14 parts of bark of Cryptomeria fortune, 6-8 parts of cottonseed cakes and 0.45-0.5 parts of compound microorganisms. The formula is scientific and reasonable, effective nutritional ingredients of the raw materials are mutually integrated and supplement one another, tillering of the wheat can be promoted, robust growth of wheat plants is promoted, the aphid damage rate of the wheat is reduced, absorption and conversion of zinc elements can be effectively promoted, the withering rate of wheat seedlings can be effectively reduced, the thousand kernel weight and the yield of the wheat are increased, and more economic benefits are brought to a grower.

The invention discloses an ultraviolet-light self-cleaning ceramic and a preparation method thereof. The method comprises the following steps: according to proportion, mixing kaolin, quartz, dolomite, clay, perovskite, smithsonite and sandstone rock, performing ball-grinding according to the mass ratio of raw materials to grinding balls of 1:(3-4) to obtain petuntse; grouting the petuntse, finishing blanks, sintering for 1 to 2 at 400-500DEG C, continuing heating, retaining for 2-3h at 700-900DEG C, heating to 1250-1350DEG C, and sintering to obtain the ultraviolet-light self-cleanness ceramic. The product has ultraviolet-light self-cleanness, and the high-efficient cleanness effect can be achieved by matching the ceramic with an ultraviolet light on the toilet product.
