   Regarding the question of how much is a gram of waste silver paste to recycle, half a dollar for junk silver shows that the price of waste silver is priced according to the market. We take the waste silver paste and dissolve it in water, and then accurately weigh the processed powder. Slowly add to the solution, keep the temperature in the electric hot water bath and then add glucose, the mixture turns black immediately. Stir constantly until the mixture is clear and brown, so that we will collect small silver balls. Regarding the question of how much is the price of scrap silver per gram, we think that how much rubbish silver I should own for one gram should be the preferred solution. Regarding the relatively good experimental waste silver paste recovery conditions of the ascorbic acid high-priced waste silver paste recovery method, we can get a very intuitive answer from the orthogonal test of the table and its trend graph.


 
   First look at the graph, the curve of the influence of the reaction time on the test indicators The trend can be seen, as the reaction time increases by a certain amount. There is also the issue of how much silver paste is recovered per gram. The price of waste silver will also increase. When it reaches the curve, the curve will show an inflection point. If you continue to increase the reaction time, the yield begins to decline. The curve trend of the influence of ammonia water consumption on the recovery rate of high-priced waste silver paste can be seen, when the amount of ammonia water is used, the sale of waste silver is the highest. If the amount of ammonia water is increased, the recovery rate of high-priced waste silver paste begins to decline. Obviously, the curve trend of the graph tells us intuitively that when the amount of ascorbic acid is one gram of silver, the recovery rate of high-priced waste silver paste is the highest. The best price for garbage silver bags is derived from this. The better test condition for the recovery of silver from high-priced waste silver paste by ascorbic acid method is one gram of silver, that is, the better condition for recovery of high-priced waste silver paste is the reaction time,


 
   the volume of ammonia ascorbic acid The volume is one gram of silver. Accurately weigh the processed powder into a beaker, add a small amount of water to the beaker, mix evenly, keep the temperature in an electric hot water bath, and then stir and add hydrogen peroxide dropwise to immediately generate silver to make it Respond fully and collect the best place to buy trash silver. In the reaction in dilute hydrochloric acid, take dilute hydrochloric acid in a beaker, suspend the treated powder in dilute hydrochloric acid, and keep the temperature in an electric hot water bath. Take the zinc powder and add it in three parts, and stir it quickly. The gray silver precipitates, continue to stir until the reaction is complete, and collect the silver powder. React in ammonia water. Accurately weigh the treated powder and dissolve it in ammonia water, dilute with water until it is kept at a constant temperature in an electric hot water bath, and add zinc powder. The above is the full text of the scrap silver price per gram. I hope it will be helpful to everyone!
