The application aims at recovering scheelite from low-grade refractory ore, improves the separation effect of scheelite and gangue minerals, improves the scheelite recovery rate and the concentrate grade, and improves the economic benefit.

A preparation method of a new type of environment-friendly natural latex product. The method comprises the following steps: S1, preparation of a sodium salt solution of shellac resin; S2, adding potassium pyrophosphate, potassium oleate, potassium ricinoleate and sulfur dispersion into natural latex, and stirring and aging to obtain a mixture A; S3, adding calcium salt aggregates of shellac resin and a rubber deodorant into the mixture A, stirring uniformly, immediately transferring the mixed glue liquid into a foaming machine to perform foaming, injecting zinc oxide dispersion and sodium fluosilicate dispersion during the foaming process, and injecting the foamed latex mixture into a pillow mold to enter a steaming oven for vulcanization; and S4, washing and vacuum drying the semi-finished product of the latex product, and completing the production. The method is convenient to process and reliable in environmental protection.

The application discloses a method for producing high-quality machine-made sandstone by using waste glass, and belongs to the technical field of building materials, and comprises the following steps: (1) crushing waste glass to obtain waste glass powder; (2) adding an alkali solution into the waste glass powder, mixing, stirring and reacting at a temperature of 65-85 DEG C for 3-5 hours to obtain a reaction product; and (3) uniformly mixing machine-made sandstone and sodium fluosilicate, then adding the mixture into the reaction product, continuously stirring, and continuously feeding carbon dioxide gas into the container until the liquid in the container is completely absorbed. The waste glass powder is reacted with the alkali solution to obtain water glass, and the water glass is solidified and coated on the surface of the machine-made sandstone, so that the strength and surface smoothness of the machine-made sandstone are improved. Moreover, the particle size distribution of the waste glass powder is reasonably designed, the graded glass particles with the corner part removed are mixed into the machine-made sand as aggregate, and the overall grading distribution of the mixed machine-made sand is improved.

The application provides a method for producing microcrystalline glass from phosphogypsum, microcrystalline glass and a phosphogypsum-based mixed raw material. The method for producing microcrystalline glass from phosphogypsum comprises the following steps: obtaining the phosphogypsum-based mixed raw material, wherein the phosphogypsum-based mixed raw material comprises, in terms of mass fraction, 30-45% of phosphogypsum, 20-40% of quartz sand, 5-10% of soda ash, 5-10% of sodium fluosilicate and 5-15% of feldspar; melting and forming the phosphogypsum-based mixed raw material to obtain a glass substrate; and performing heat treatment on the glass substrate to obtain the microcrystalline glass. The application creatively applies the phosphogypsum to the preparation of the microcrystalline glass without desulfurization treatment, significantly simplifies the steps, reduces the energy consumption and cost, and is simple and efficient, and is worth promoting.
