The application discloses a preparation method of a chaenomeles fruit bio-fertilizer additive, which comprises the following steps: collecting chaenomeles fruit seeds, adding water to the chaenomeles fruit seeds to stir and extract, and concentrating to obtain a concentrated solution containing chaenomeles fruit seed gum, and then crushing the chaenomeles fruit seeds to obtain chaenomeles fruit seed powder; taking chaenomeles fruit residues, crushing the chaenomeles fruit residues, mixing the crushed chaenomeles fruit residues with citric acid, the chaenomeles fruit seed powder and water, filtering, mixing the filtered mixture with water and a compound microbial agent to ferment, and continuously fermenting the mixture to obtain a primary fermentation product; taking the concentrated solution, mixing the concentrated solution with biochar, chitosan and potassium persulfate to react, adding the secondary fermentation product to the mixture to stir and mix to obtain a mixture, and then sending the mixture to a granulator to granulate to obtain the chaenomeles fruit bio-fertilizer additive. The application fully utilizes the waste, such as peels, fermentation residues, rotten fruits and chaenomeles fruit seeds, generated in the processing of chaenomeles fruits to produce the high-quality chaenomeles fruit bio-fertilizer additive, and solves the problem of poor utilization effect of the existing chaenomeles fruit waste.

This invention relates to the field of food analysis and testing technology, specifically disclosing a method for predicting the papaya seed powder content in black pepper powder based on ICP-MS analysis of characteristic trace elements. The method includes: Step 1, detecting the relative content of characteristic trace elements in the sample to be predicted, including Zn, Tl, and Mo; Step 2, inputting the data into a prediction model and outputting the adulteration content of the sample, Y = 0.005S1 + 0.252S2 - 0.059S3 - 0.031, where S1 represents Zn, S2 represents Tl, and S3 represents Mo. This invention provides a faster, simpler, and more accurate new method for predicting the adulteration content of papaya seed powder in black pepper powder.

The application discloses a method for floating tin and zinc in polymetallic sulfide ore, which comprises the following steps: grinding and thickening the polymetallic sulfide ore, then stirring and desliming the polymetallic sulfide ore by adding papaya seed glue and polyacrylamide, grinding and thickening the polymetallic sulfide ore, and floating the polymetallic sulfide ore by adding a flotation agent A to obtain flotation concentrate C and flotation tailings D, wherein the flotation agent A comprises ethion, zinc sulfate, cationic starch, lime and pine oil; grinding and thickening the flotation concentrate C, and floating the flotation concentrate C by adding a flotation agent F to obtain lead concentrate and flotation tailings G, wherein the flotation agent F comprises sodium tartrate, zinc sulfate, sodium diethyl dithiocarbamate, ethion and pine oil; adding sulfuric acid solution to the flotation tailings D after concentration, and grinding and magnetic separating the flotation tailings D, adding a flotation agent to the magnetic separation tailings to obtain flotation concentrate J, and obtaining tin concentrate by table gravity separation of the flotation concentrate J. The application solves the problem of poor flotation or gravity separation effect of fine-grained tin ore, and can improve the recovery rate of tin and zinc in the polymetallic sulfide ore.
