The present invention relates to a method for melting and smelting non-ferrous metals, in which sulfide ore such as lead, zinc, copper, oxide ore, scrap, etc. are melted and smelted using limestone, soda ash, barium carbonate, etc. as a solvent. ―
A molten product characterized by significantly reducing the content of lead, zinc, copper, etc. in the slag by producing so-called ferrite slag based on calcium oxide, iron oxide-sodium oxide, and iron oxide-barium oxide. It provides an alchemy. In conventional melting and smelting of sulfide ores such as lead, zinc, and copper, and scrap, silica is added as a solvent to produce so-called silicate slag, which is iron oxide-silica system or iron oxide-silica-calcium oxide system. It was customary to do so. That is, in conventional non-ferrous smelting, silicate slag (also called silicate slag) is mainly used, and its most common constituent oxides are silica (SiO 2 ) and iron oxide (FeO), with secondary components Among iron oxides, the allowable abundance of magnetite ( Fe 3 O 4 ) was limited. It is well known that in such conventional slag, considerable amounts of lead, zinc, copper, gold, silver, etc. enter the slag, resulting in losses. The present invention provides a method for smelting non-ferrous metals that uses a new slag in place of the conventional silicate slag to greatly reduce the loss of each valuable metal. system slag,
It is characterized by reduction smelting of oxide ore in the presence of one or more types of sodium ferrite-based slag or barium ferrite-based slag, or oxidation smelting of sulfide minerals into crude metals in a molten state. The new type of slag named ferrite slag by the present invention is iron oxide and calcium oxide (calcium ferrite slag), iron oxide and sodium oxide (sodium ferrite slag), or iron oxide and barium oxide (barium ferrite slag).
The main component is 15-35%, usually around 20% CaO or Na 2 O, or 20-50% BaO.
Silica, which was considered an essential component of traditional slag, is a secondary component, containing CaO or Na 2 O, 1/5 of BaO.
It contains almost no silica. Unlike silicate slag, this ferrite slag can hold a large amount of Fe 2 O 3 and therefore can be used in a wide range of smelting conditions, from strongly reducing to strongly oxidizing. In addition, since the iron oxide holding capacity is high, the amount of slag is generally small. Melting point is 1100
It has various characteristics such as being the same or lower than silicate slag at ~1200℃, and its viscosity and surface tension are extremely low, allowing for rapid and complete smelting reactions. It was found that the migration of lead, zinc, copper, etc. to the metal can be significantly reduced. Because slag containing considerable amounts of CaO and Na 2 O is strongly basic, it has traditionally been used to oxidize and smelt harmful elements in crude metals such as As, Sb, and P to remove them as acidic oxides. In some cases, the conditions were such that a considerable amount of silica coexisted or iron oxide was absent, which did not correspond to the above-mentioned ferrite slag.
In addition, recently, CaO
―Fe 3 O 4 ―Cu 2 O-based ferrite slag is used in some cases, but this slag was used to smoothly convert matte into blister copper. However, it was not adopted with the intention of reducing the loss of valuable metals to slag (for example, Japanese Patent Publication No. 51-5337). The method of the present invention will be specifically explained below according to representative test examples and examples. Since the loss of metal to slag is usually in the form of its oxides, it is related to the oxygen partial pressure of the smelting conditions; if it is reducing and the oxygen partial pressure is low, the slag loss will be small, and if it is oxidizing and oxygen The higher the partial pressure, the higher the slag loss. Therefore, under the magnitude of slag loss, FeO
―Fe 2 O 3 ―SiO 2- based silicate slag and FeO―
A comparison will be made with respect to Fe 2 O 3 -MO-based ferrite slag (M is Ca, Ba or Na 2 ) with the oxygen partial pressure kept constant. First, molten lead and slag are heated at 1200℃, and the oxygen partial pressure is
In the case of coexistence equilibrium under 10 -12 atm, 10 -10 atm or 10 -9 atm, the lead content in slag is as shown in Table 1. The data is for ferrite slag containing FeO--Fe 2 O 3 as well as Na 2 O, CaO, and BaO at the indicated concentrations.

（マグネシヤルツボ）での例である。[Table] Copper loss in ferrite slag is usually about 60% of that in silicate slag, but the difference becomes larger when it is oxidizing and the oxygen partial pressure is high. In the case of zinc smelting, the zinc content in the slag varies not only by the oxygen partial pressure but also by the metal zinc vapor pressure in the coexisting gas phase, so it is not as simple as in the case of lead or copper, but in conclusion Zinc loss to ferrite slag is about 1/3 of that in silicate slag. In order to obtain the above effects, the composition of ferrite slag should be 15 to 35% CaO or Na 2 O.
% or 20 to 50% BaO is suitable. As mentioned above, when comparing the concentration of valuable substances dissolved in slag, ferrite slag has a significant advantage over conventional silicate slag, but there are other factors that make ferrite slag even more advantageous in actual smelting. There are two. One is that ferrite slag requires less slag, generally 60 to 80% of that of silicate slag. Another reason is that unlike silicate slag, ferrite slag has a low viscosity and there is no concern that magnetite solids will precipitate, so slag loss due to suspension is extremely small. Taking all these factors together, in actual smelting using ferrite slag, the slag loss is significantly smaller than in the conventional method, and the metal recovery rate is increased. Example 1 As a test based on actual smelting, Pb:Fe=4:
Silica or lime (CaO) was added to a lead-lead oxide-iron oxide mixture prepared at a ratio of 1 to form a suitable slag, and reductive melting was performed at 1200°C. Table 3 compares the obtained silicate-based slag and calcium-ferrite-based slag, and shows their composition, amount, and ratio of slag loss lead to the amount of lead charged. No. 1 is an example under the most reducing conditions (using an iron crucible), and No. 2 is an example under considerably oxidizing conditions (magnetic crucible).

結果を第４表に示す。[Table] As shown in the results in Table 3, lead loss to slag is significantly smaller when ferrite slag is used. Especially under oxidizing conditions, silicate slag has a high magnetite content and a high viscosity.
The lead loss due to suspension increases and the amount of slag produced also increases, so the loss to the slag becomes very large.
Even under the same oxidizing conditions, there is less loss to the ferrite slag. Example 2 An experiment similar to Example 1 was conducted using a charge of Cu:Fe=4:1 and a system of molten steel and slag at 1250°C.
I did it at Melt test results under highly oxidizing conditions are shown in Table 4.

明らかである。[Table] In this case as well, silicate slag has a large amount of slag and suspension loss increases, so the copper loss is more than twice that of calcium ferrite slag. It is also clear from the table that a large amount of Fe 2 O 3 is present in the ferrite slag.
