technical field

The invention relates to the technical field of stone coal vanadium ore ripening, in particular to a stone coal vanadium ore ripening production equipment and a stone coal vanadium ore ripening production method.

Background technique

Vanadium metal is widely used in iron and steel, metallurgy, chemical industry, new energy and other fields. Stone coal is a kind of black carbonaceous shale, which is formed by accumulation under reducing conditions after the death of shallow sea bacteria and algae. In addition to silicon, stone coal often contains vanadium. Stone coal vanadium ore accounts for 30% of the total production raw materials of vanadium products in my country, and is an important raw material for the production of vanadium products in my country.

At present, the methods for extracting vanadium from stone coal vanadium ore mainly include two categories: roasting method and acid leaching method. The traditional vanadium extraction method of stone coal vanadium ore is sodium roasting method. This method has a simple production process and mature technology, but there are problems such as low vanadium resource recovery rate and large three-waste production and discharge, and it is difficult to meet the current national environmental protection emission standards. The acid leaching method mainly includes direct acid leaching method and sulfuric acid aging method. The acid leaching method is energy-saving and clean, and avoids a large amount of waste gas produced by the traditional roasting method, and has a good application prospect. The direct acid leaching method is only suitable for the treatment of weathered stone coal. For the primary stone coal whose vanadium mainly exists in mica-like aluminosilicate minerals, it is difficult to extract vanadium, and the sulfuric acid aging method can effectively treat this kind of stone coal. Can improve the leaching rate of vanadium.

Chinese patent CN105483398A proposes a method for extracting vanadium by maturing vanadium-containing minerals. First, the stone coal is crushed and ground to 5mm, and 8% water, 1% phosphoric acid, and 16% concentrated sulfuric acid are added respectively, and the clinker is matured at 105°C for 24 hours. Ratio 2:1 leaching for 2 hours, the leaching rate of vanadium is greater than 85%. Chinese patent CN102912123A proposes a method for sulfuric acid aging to decompose stone coal vanadium ore. First, the stone coal is ground to -74 μm, and then 3%-8% water, 3%-8% sodium sulfate, and 15%-30% concentrated sulfuric acid are added. Finally, use concentrated sulfuric acid to release heat when it meets water, heat preservation and aging for 12h-48h, clinker at 85°C-100°C, liquid-solid ratio 1.5:1-3:1, leaching for 2h-10h, the leaching rate of vanadium is greater than 80%.

At present, the sulfuric acid aging process is operated intermittently, the conditions of the production process are difficult to control, and the production efficiency is low.
