Fire refining bismuth technical and economic indicators include straight refining yield, recovery of refining, alkali consumption, consumption of zinc, chlorine consumption, coal consumption, the passing rate, product rate and the like. First, refining straight yield Refining refers to direct yield pure bismuth in an amount of pure refined bismuth output amount of bismuth into the material in the ratio of production practice, since the secondary slag and silver in addition to copper-depleted slag returns compartment batch process, the amount of slag not weighed It has not been analyzed, and it is only used as the slag of this batch to offset the slag invested in this batch. Therefore, there is a slight discrepancy between the calculation of the direct yield and the actual situation in each batch. When the direct yield is calculated on a monthly basis, the amount of slag remaining last month and the amount of slag remaining in the month are considered, so the straight-through yield per month is more accurate. The calculation formula is: Second, the refinement recovery rate The amount of pure sputum in the refined product: (the amount of pure hydrazine in the input material - the amount of pure hydrazine in the returned material - the amount of pure hydrazine in the transferred material), that is, in the denominator term, the secondary copper slag and lean slag that are returned should be considered The amount of pure sputum and the amount of mash after casting, but also the amount of pure strontium transferred to the melted silver slag and transferred to the crude slag, but also the transfer to recover zinc Chloride The amount of pure ruthenium in the zinc chloride slag and the lead chloride residue recovered. Refining recovery rates are calculated on a monthly and yearly basis and are not calculated in batches. Its calculation formula is: In the formula, the amount of pure bismuth (in kilograms); Bi-input amount of pure ruthenium (kg); Bi return - the amount of pure ruthenium in the returned material (kg); The amount of pure rhodium (kg) in the Bi-transfer material. The direct yield and recovery rate of refining are the main indicators for measuring the level of production technology. They are related to the quality of rough materials, equipment conditions, choice of process flow, technical sufficiency of workers, production organization and management, and directly reflect the production level of enterprises. Directly affect economic benefits. Third, product qualification rate Product qualification rate refers to the ratio of qualified product to product quantity. Its calculation formula: There are two concepts of qualified products: one is considered to be a product that meets the quality standards (national standard, ministry or enterprise standard); one is considered to be a product produced according to the quality standards arranged by the production plan. The latter concept is often used in practice. Fourth, what is the first grade rate? The ratio of the number of primary products to the total number of products in the product. Its calculation formula is: Product qualification rate and first-class product rate are indicators for measuring product quality. For the quality requirements of the product, it should be fixed by sales, that is, according to the market needs to develop production plans to guide production, and should not blindly pursue high-purity products that do not consider market needs and economic benefits. 5. What is the alkali consumption, chlorine consumption, zinc consumption and coal consumption? The amount of solid alkali, chlorine, zinc ingots, and fuel coal consumed in the production of one ton of refined sputum (kg). Its calculation formula is: Alkali consumption, chlorine consumption, coal consumption and zinc consumption are indicators for measuring the consumption of auxiliary materials, which directly affect production costs and economic benefits. Therefore, we strive to reduce these consumptions. The influencing factors of these indicators are mainly related to the organization and management of production. It is related to the technical proficiency and responsibility of the operator. Calcium Sulfate : the commonly used calcined gypsum is the best coagulant for tofu production. In addition, calcium sulfate can also be used as thickening agent, acidity regulator and flour treatment agent.

Calcium Chloride: generally not used as tofu coagulant, can be used as low methoxy pectin and sodium alginate coagulant. It can also be used for making cheese, and can also be used as hardener for assorted vegetables, tomatoes and lettuce.
Magnesium Chloride: Salt brine is commonly used to make old tofu and dried tofu. Salt brine tofu has a unique flavor of tofu.
Propylene glycol: It can be used as a moisturizer and softener for bread, candy, packaged meat, cheese, etc. It can increase the elasticity of noodles, increase the flavor, whiteness and luster of tofu, and it can also be used as food antifreeze liquid.
EDTA salts: including disodium ethylenediaminetetraacetate and disodium calcium ethylenediaminetetraacetate. EDTA salts have the function of chelating metal ions, eliminating harmful effects caused by metal ions, preventing discoloration, deterioration, turbidity caused by metal, preventing loss of vitamin C due to oxidation, improving food quality, and are calcium nutrients. Fortifier.
Tin disodium Citrate : also known as 8301 color protection agent, is white crystalline, very soluble in water, easy to absorb moisture and hydrolyze, very easy to oxidize, mainly used in fruits and vegetables, edible fungi canned, antioxidant color protection role.
Gluconic acid-delta-lactone: Gluconic acid-delta-lactone can be used as a coagulant to make lactone tofu, as a preservative to preserve fish, poultry, shrimp, etc., as a sour agent to be used in juice drinks and jelly. As a chelating agent, it can be used in grape juice or other berry wine, dairy products and beer to prevent the production of tartar, milk stone and beer stone.
Herb extract: it is obtained by crushing, boiling, extracting, filtering, concentrating, and spray drying with dried herbs. It is light yellow solid powder. It is a gelatinous polysaccharide contained in the grass and can be used to make cake foods.
Microbialtransglutaminase is an enzyme that catalyzes the intra (or intra) acyl transfer reaction between proteins, resulting in covalent cross-linking between proteins (or polypeptides), and can catalyze the intra-molecular and inter-molecular covalent cross-linking of protein polypeptides, thereby improving the structure and function of proteins. It has significant effect on protein properties such as foaming, emulsifying, emulsifying stability, thermal stability, water retention and gel ability, and then improves the flavor, taste, texture and appearance of food. It can be applied to aquatic products, ham, sausages, noodles, tofu and so on.
In addition to the above substances, they also include phosphoric acid, sodium lactate, calcium lactate, calcium Carbonate in acidity regulators, alum in bulking agents, polyglycerol monofatty acid esters in emulsifiers, tween, stearic lactate, chymosin in enzymes, D-mannitol, maltitol, lactosol and sorbitol in sweeteners. The water retention agents include trisodium Phosphate , disodium hydrogen phosphate, pectin, propylene glycol alginate, xanthan gum, chitin, polydextrose, carrageenan, cordlan gum, hydroxypropyl starch and so on.
