Abstract
The invention discloses a method for recycling lead-tin in silver separating residue of copper anode slime of a circuit board and relates to a method for recycling silver separating residue of copper anode slime of the circuit board by a wetting method. The method comprises the following steps of: stirring silver separating residue, water, hydrochloric acid, calcium chloride and sodium chloride for 0.5 to 2.0h under proper temperature according to requirements, filtering and obtaining lead separating liquid and lead separating residue; carrying out displacement to the lead separating liquid by using excess iron powder, filtering and obtaining spongy lead and displaced liquid; using sodium hydroxide to adjust pH value of the displaced liquid till the precipitate is not generated; and returning lead separating procedure after the iron is precipitated. The lead separating residue, the sodium hydroxide and sodium nitrate are mixed evenly to carry out roasting with the temperature of 350 to 500 DEG C, and then are added with water and filtered, thus obtaining the sodium stannate. Compared with the prior art, due to the adoption of a full-wetting process, the method reduces a large amount of waste gas and dusts in the process of pyrometallurgical treatment; the liquid after the iron is precipitated contains the main compositions of hydrochloric acid and sodium chloride; and the method can return acid pickling procedure, reduce discharge of waste water and lower cost, and is characterized by simple technique, no pollution and the like.
Description
Technical field
The present invention relates to the method for hydrometallurgic recovery anode sludge slicker solder, particularly relate to the method for hydrometallurgic recovery silver separating residue of copper anode slime of circuit board slicker solder.
Background technology
The silver-colored slag of branch is the recrement after copper anode mud extracts valuable elements such as precious metal gold and silver, platinum, palladium and copper, selenium, tellurium.Copper anode mud is in the electrorefining process, forms with the various materials that are insoluble to electrolytic solution than the element that copper current potential is higher, and its composition depends primarily on composition, castability and the electrolytic technical qualification of copper anode, and its productive rate is generally 0.2～0.8%; It contains Au, Ag, Cu, Pb, Se, Te, As, Sb, Bi, Ni, Fe, S, Sn, SiO usually
2, Al
2O
3, platinum metals and moisture.Derive from the anode sludge of copper sulfide concentrate, contain more Cu, Se, Ag, Pb, Te and a small amount of Au, Sb, Bi, As and gangue mineral, the platinum metals seldom; And the anode sludge that derives from copper-Ni sulphide mine contains more Cu, Ni, S, Se, and precious metal is mainly the platinum metals, and the content of Au, Ag, Pb is less; The circuit card composition brass anode sludge that electrolysis is produced then contains higher Pb, Sn, and precious metal mainly is Ag, Au and platinum metals, and the silver-colored slag of branch that precious metal obtains after extracting contains Pb, Sn is higher, has very high recovery value.
It is few that domestic slicker solder to minute silver-colored slag is recycled research, and each smeltery is many will to divide silver-colored slag to return copper reverberatory furnace workshop section (application number: 200810049459.5), increased the furnace charge processing, and slicker solder content builds up but, might influence the quality of anode copper.So further development and use are waited until dividing silver-colored slag all temporarily to stack on one side by most of now producers.Minority producer sells some special precious metals with it and reclaims the business processes recovery; carry out the extraction (patent application 90103200.X, 97105925.X, 200710303815.7) of some precious metal element; the recovery of this extensive style is with some valuable metal in the waste slag; and do not consider environment protection in the technology, not only wasted resource but also caused new environmental pollution.
Lead mainly is with PbSO in the silver-colored slag of branch
4, PbCl
2, PbS, PbO and Pb form exist, wherein lead sulfate accounts for more than 95%.And tin is mainly with SnO
2Form exists, and accounts for more than 95% of tin total amount.Soak plumbous theory, PbSO according to chlorination process
4, PbCl
2Solubleness in water is very little, but two kinds of precipitations are dissolved in the dense NaCl solution of heat, so under the hot conditions, with the aqueous hydrochloric acid is medium, add sodium-chlor, lead sulfate is dissolved in the salt solution, and lead sulfide, metallic lead and plumbous oxide also are converted into lead chloride accordingly and extract from minute gold and silver slag under hydrochloric acid and sodium chloride medium condition.Tindioxide is stable tetravalence structure, is insoluble to bronsted lowry acids and bases bronsted lowry.Therefore, tindioxide must be made the transition the form that can be dissolved in acid, could realize that the wet method of tin is extracted.In the compound of tin, sodium stannate can be water-soluble, can obtain by alkali fusion.
Summary of the invention
Purpose of the present invention mainly solves the anode sludge and divides slicker solder recovery problem in the silver-colored slag, not only can guarantee that efficient recovery divides the valuable metal of the slicker solder in the silver-colored slag, and processing technological flow is short, equipment is simple.
The anode sludge of the present invention divides silver-colored slag slicker solder recovery method as follows:
To divide silver-colored slag to dissolve by design requirements water, hydrochloric acid, calcium chloride and sodium-chlor, water wherein: divide silver-colored slag=5: 1～10: 1, concentration of hydrochloric acid is 50～100g/L, calcium chloride concentration is 100～300g/L, sodium chloride concentration is 150～300g/L, 75～95 ℃ are stirred 0.5～2.0h down, filter and obtain plumbous liquid of branch and lead separated slag; Divide plumbous liquid to replace, filter and obtain spongy lead and displaced liquid with excess iron powder; Displaced liquid is regulated the pH value up to not producing precipitation with sodium hydroxide, and liquid returns branch splicer preface behind the heavy iron; Lead separated slag adds sodium hydroxide and SODIUMNITRATE mixes, and forms the lead separated slag mixture, wherein sodium hydroxide: divide silver-colored slag=1: 10～3: 10, SODIUMNITRATE: divide silver-colored slag=1: 100～5: 100; The lead separated slag mixture is carried out 350～500 ℃ of roasting 1.0～3.0h, roasting sand is placed 24～48h in air, add entry and carry out water logging, stir 0.5～1.0h, water: divide silver-colored slag=3: 1～5: 1, filter and obtain sodium stannate.
Compared with prior art, because the present invention has adopted wet processing process, reduce the large quantity of exhaust gas and the dust that produce in the pyrogenic attack process; Liquid and evaporation back liquid can return the plumbous and water logging operation recycle of branch respectively behind the heavy iron, reduce discharge of wastewater, reduce cost.
Characteristics such as the present invention has simple for process, and raw materials used and equipment is all more common and cheap, pollution-free.
