Problems solved by technology

Scientists in ancient my country and Western countries realized their dreams in their later years and invented and created alchemy. However, both methods have their technical disadvantages. These methods are old and ancient, and the dissolution of gold and silver is slow for quartz vein gold ore containing a lot of sulfur. It is difficult to leach, and a considerable part of even up to 10% of the gold and silver remains in the vein gold ore
This kind of method is used to smelt brass-containing alloy gold and alloy silver, which are hard and only used as gold and silver jewelry. The scope of use in the field of science and technology is limited, so users rarely demand brass-containing alloy gold, silver
[0003] And my previous two invention patents have the technical disadvantages of using strong water and prescription saltpeter and other four kinds of medicines, gathering heat and drying under light at a nanometer temperature of 40°C to obtain thousand pure gold and silver

Embodiment 1

[0012] Embodiment 1. 1. the present inventor exploits the refractory sulfur-containing quartz vein gold ore in precious metal mines. After crushing and sieving, get the gold ore powder, scoop half of the water with a pottery pot, take 15 grams of bittern with a balance, and mix well Wash by hand, most of the impurities are separated and removed with the rotation of water, gold chips sink to the bottom, and the brine is discarded. Take golden flakes at a solid-liquid ratio of 6:1, and take the four flavors of alchemy: emerald alum: calomel: brine: alum. Then pour 10 times of river water, stir evenly, adjust PH=7.0, cover, put on the fire and heat for 35 minutes to boil, then extract for 15 minutes, the gold is oxidized and decomposed by hydrogen peroxide to completely react to form a complex alloy solution, which dissolves In alchemy medicine, all silver except gold reacts with magnesium chloride in the brine to form impurities such as silver chloride and silicon dioxide. A lay...

Embodiment 2

[0014] Embodiment 2. 1. the present inventor exploits the refractory sulfur-containing quartz vein gold ore in the precious metal mine, through pulverization, sieves through the eyes, gets the gold ore powder, scoops half of the water with a pottery pot, takes by weighing 15 grams of bittern with a balance, mixes evenly Wash by hand, most of the impurities are separated and removed with the rotation of water, gold chips sink to the bottom, and the brine is discarded. Take golden flakes at a solid-liquid ratio of 6:1, and take the four flavors of alchemy: emerald alum: calomel: brine: alum. Then pour 10 times of river water, stir evenly, adjust PH=7.0, cover, put on the fire and heat for 35 minutes to boil, then extract for 15 minutes, the gold is oxidized and decomposed by hydrogen peroxide to completely react to form a complex alloy solution, which dissolves In alchemy medicine, all silver except gold reacts with magnesium chloride in the brine to form impurities such as silv...

Abstract

The invention discloses a method of separating and purifying gold and silver. A natural mineral and plant drug is prepared from the following components in percentage content: 40% of nickel vitriol NiSO4. 7H2O, 10% of calomel HgCl2 and HgNO3, 30% of brine MgCl2, MgBr2, MgSO4 and Na2SO4 and 10% of alum KAI(SO4)2. 12H2O in the formula ratio of 1 : 1 : 2 : 2; an additive is prepared from 1 parts of 3to 80% of hydrogen peroxide (H2O2) and 1 parts of 80% of reducing sugar contained in straw; a reducing drug is prepared from black ant, human urine and a substance which is obtained from the photosynthesis light energy reaction of green plant paddy, wherein the black ant contains the chemical components: formic acid (methane acid) and ammonia, the human urine contains ammonia, urea, uric acid, oxalic acid and sulfuric acid, and the percentage content of the human urine is 60%; by chemical dosage, 3.5 times of black ant is employed to carry out reduction; and the gold and the silver are separated and purified from indissolvable sulfur-contained quartz vein gold ores of minerals by a kan and li water method or fire method.

Description

Technical field: [0001] The method for separating and purifying gold and silver is from mineral refractory sulfur-containing quartz vein gold mine, which belongs to the field of separating and purifying gold and silver precious metals by water method or fire method. Background technique: [0002] For example, Baopuzi, an ancient Chinese scientist, made a detailed study of Huangbaizhu in his "Shentongqi" in his later years: he made a combination of seven medicines such as mercury and sulfur, and then mixed the hardware into a ceramic crucible for melting. The alchemy left in the "Deed" was refined into false gold, and the final product was alloy gold containing brass. Another example is the "Compendium of Materia Medica" by Li Shizhen, a great medical scientist in the Ming Dynasty. It is recorded that a large number of alchemy drugs include realgar, Hu Tonglei, blue vitriol, anoint, etc., and they are turned into gold, silver and copper alloy gold with the empty green point o...
