Description of the invention (1) Description of the improved method of leaching ore Cross-reference related applications This application claims the benefits of the tentative application USSN60 / 120,820 which was filed on February 19, 1999. BACKGROUND OF THE INVENTION The oxides of cobalt (Co), nickel (Ni), titanium (Ti), copper (Cu), molybdenum (Mo), lead (pb), zinc (Zη), gold (Au), and silver (Ag) are Important inorganics. Various methods exist for recovering these compounds from where they were found. For example, autoclave methods are often used to recover Co, Ni and Ti oxides. These methods are costly and laborious. Mo oxides have been leached out in the past by the hydrogen acid method. Cyanide, thiosulfate, and sulfide are used to leach Au and Ag metals and oxides. CU, Zn, and Pb can be leached from sulfuric acid. Rutile (Ti02) is an inorganic substance that can be used for many purposes. Among other uses, it is a source of titanium metal and pigments. Artificial rutile is generally considered to be any rutile made from other inorganic materials, usually ilmenite with at least 90% butadiene. High-purity rutile is 99 9% + T2. 2 High-purity rutile is generally commercially available. “Iron ore (FeTi03) is most commonly obtained in the press, and is prepared by rolling bismuth with dry lice and leaching at high temperature to convert it into artificial rutile. The leaching temperature is generally borrowed between 800 and 900 t. Vaporized iron is sometimes used in these autoclaves to increase the reaction rate at low temperatures. Z_eWin et al. (B.

In another specific example, metal ions and sulfuric acid can be used to take into account gold scrap and other recovered metal alloys. The concentration of the metal autoclave salt will depend on the specific debris mixture. This specific example can be used to selectively incorporate a specific metal or all metals into a solution. This specific example can also be used for radioactive ribosol dissolving such metals such as nickel from radioactive debris. Oxygen or other oxidizing gases, such as gas, can be added to the metal for hydration. "For some oxide ores containing multivalent transition metals such as the donors of the highly oxidized co and Mn species, the alkali metal ions can be replaced by sulfur-based reducing compounds. For example, sodium sulfite, Sodium sulfite, sodium bisulfite, sodium disulfite, or other alkali metals or sulfites, hydrogen sulfite, hydrogen sulfite, or disulfite carbonate can be used to replace alkali gold From sulfur compounds, these sulfur-based reducing compounds will help reduce the reduction of transitional gold, and open the ore by sulfuric acid to attack it.

A7 ________ β7 V. Description of the invention (18) It belongs to the original metal which does not need to be destroyed. Metallic acid salts or hypochlorites can be used with sulfuric acid to leach most metals. These techniques can be used to leach metals from sulfide minerals or from debris, residues, slag, concentrates, or soil. In another specific example, a slightly modified method using metal autologous salts can use sulfuric acid in a countercurrent decantation (CCD) loop that currently exists. This specific example will utilize fresh feed material to achieve a neutralization solution sufficient to retain iron in the solution. After the liquid-solid separation is completed, the resulting leached aqueous solution can be further neutralized in the presence of a binder to cause iron to precipitate as a hydroxide. The iron precipitate can then be partially dried and made into a sphere shape to make a pig iron feed stock solution. The liquid-solid separation method can be any method which can completely separate solids from the aqueous solution of bitumen in a relatively short time. These include methods such as cyclones, filters, centrifuges, magnetic separators and clarifiers. The most economical method for a particular plant is to remove graves or cobalt completely or shame from the tritium solution. Methods that can be used include, but are not limited to, seeding by precipitation, pH adjustment, crystallization, solvent extraction, and ion exchange. Economically priced A machines are often associated with species that can consume chemicals used to drain them. It is said that even if the consumption of species has a position in the economy, it will make the entire market 、, ，, ^,--uneconomical. This reality

Unless otherwise indicated, all percentages are by weight and all solvent mixture ratios are by volume. Example 1-Leaching of titanium and iron from ilmenite Dynamic experiments of leaching titanium and iron from ilmenite show that both are leached first 'and then titanium precipitates and slows down the leaching rate of iron. The experiment was performed with 100 g of ilmenite that was ground to 200 mesh. These tests were performed with 1000 g of 200 g / L (g / L) sulfuric acid and 120 g / L of NaCl solution. 100 g of activated carbon was added and the solution was heated to 100 ° C. The concentrations of F e and T i were monitored during a 96-hour leaching process. The results are shown in Fig. 1. The results show a mechanism in which τ i is first filtered into an aqueous solution, then oxidized, and then precipitated. When this mechanism occurs' it slows down the rate of leaching, iron. The filtered T i appeared within 1 hour. In a different but similar experiment, 100 grams of ilmenite was filtered under 10 crc in 1 liter of a solution of 200 g / liter of ΗΑ04.120 g / liter of alkali metal halide, For 72 hours, the main analytical content of iron ore is 34.0% Fe and 27.0% Ti and its particle size allows all particles to pass through a 75 micron sieve. An amount of 100 grams of activated carbon is also present in the leaching solution. The T i and Fe content in this leaching solution are monitored regularly. The experimental results are shown in Table 1. “It was dissolved and then you can see its Shen Dian. A final analysis of 5 7.4 g of residue showed that it contained only 0.67% Fe and 46.6% Ti. So 98.9% of the money has been extracted into the liquid 'while 99.7%' remains in the residue. This experiment indicates that due to the initial solubility of T i, both τ i and F e can be repeated for a short period of time; calendar effects are ideally extracted from the iron ore. .—-—.----- Zhang Yi -------- Order · --------.
