AFZ production is located on the outskirts of Armavir (formerly Oktemberyan), at a distance of 45 km. from the city of Yerevan. The territory of the factory is 3.7 hectares. Our factory is currently engaged in the production of ferromolybdenum, molybdenum oxide, non-ferrous metal salts and rhenium compounds.
We have developed and implemented a unique technology for the production of vanadium pentoxide.
The factory is equipped with a hydrometallurgy site, that allows to carry out hydro chemical processing of various types of raw materials, including off grade quality. At present, with the available capacities, the factory is able to produce up to 150 tons of ferromolybdenum and 20 tons of vanadium pentoxide per month. If necessary, production areas of the enterprise allow to increase output two or more times.
The production building consists of three spans – two longitudinal ones of 24 m and one transverse width of 24 m, the overall dimensions of the building are 48*72 m. A three-story ABK adjoins the production building from one end. The floor level in the transverse span is 6 m below the floor level in the longitudinal spans. Some of the areas of longitudinal spans have two floors. In the transverse span, crane runways are installed and a bridge crane with a lifting capacity of 10 tons runs. The material of columns, trusses and ceilings is reinforced concrete, crane girders are metal. On the same side, the premises of a precipitation chamber and a scrubber are attached to the building. On the side of the transverse passage, two brick chimneys with a height of 68 m were built. The building of the compressor station was built near two bricks.
On the covered crane overpass two inclined rotating gas furnaces with a length of 12 m are mounted, which are designed for calcining the concentrate. The capacity of one furnace is 2.5 tons of concentrate per physical weight per day. The waste gases through the cyclone filter enter the precipitation chamber. After the precipitation chamber, two smoke exhausers are installed, and after them a scrubber. Nearby there is a pool for neutralizing sulfuric acid from the scrubber.
The batch preparation section consists of a single ball mill with a capacity of 10 tons per day, a mixer, a stirrer (drunk barrel), 2 crushers, bins, storage tanks, etc. There is an inclined rotary kiln for drying the shredded components of the charge.
The ditch in which the melt is produced has three locations for the simultaneous installation of reactors. The are 4 reactors. Weighed components of charge are carried out once on the floor lever weighers. At the end of the reactor loading, a gas cone is put on it and ignition of the melting is carried out manually with the help of an electric arc. The melting takes place very intensively with a large emission of exhaust gases , gas trapping and gas cleaning is carried out with the help of an installed air purification system with a capacity of 125 kilowatts. The exhausts are filtered and discharged to the chimney. Based on the current state of the equipment, the aluminosilicothermy site can do two smelts per day, which, with continuous operation, will allow the production of 200 tons of ferromolybdenum in a physical weight per month. Currently, the workshop successfully processes vanadium that contains concentrates. The workshop can take up to 200 tons of raw materials per month. There are 5 inclined rotating furnaces for sintering and firing semi-finished hydrometallurgy. The area of the factory allows expanding any of the sites based on the long-term development strategy of one or another direction.
The fragmentation site of ferromolybdenum consists of two jaw crushers.
The finished goods warehouse is located in the “basement” of the longitudinal casing. There are electronic floor scales, gates for the arrival of a lengthometer in the warehouse. Loading of big bags is possible with a loader.
There is a 30-ton ball mill in which 100% of the formed slag is ground. After that, all the slag comes to the flotation unit, where the particles of ferromolybdenum are separated, and a ferromolybdenum concentrate containing up to 50% ferromolybdenum is recovered, which is returned to the melting. As waste, slag sand is formed, which is disassembled by local residents for construction work.
The site was built for the purpose of processing molybdenum-containing catalysts used in the oil industry. The technology also allows processing of vanadium and tungsten catalysts and concentrates of substandard quality.
