Jan 15, 2021 Separation and extraction to obtain vanadium, titanium and iron products Took 10 mL of the above pregnant solution in a separating funnel and adjusted its pH to 1.6 with collected ammonia.
The invention discloses a method for separating vanadium-titanium magnetite to extract iron, vanadium and titanium, comprising the following steps of: magnetically selecting raw magnetite, that is, acquiring iron-vanadium concentrate and tail magnetite after performing magnetic selection on the vanadium-titanium magnetite; sorting titanium concentrate from the tail magnetite, that is
Sep 01, 2019 The separation of titanium (Ti) (IV) in acidic leach solutions of vanadium slag by solvent extraction with trioctyl tertiary amine (N235) is proposed. Because the leach solutions contain a lot of vanadium (V) and iron (Fe) impurities, the effects of various conditions on the separation of Ti, V, and Fe were investigated.
U.S. Patent Number 10316392 for Method for converting and separating vanadium, titanium, and iron from vanadium-titanium-iron concentrate in one step
separation of titanium–iron and the utilization of titanium slag, was expected to achieve comprehensive utilization of vanadium, titanium, and iron . In most cases, vanadium elements of vanadium–titanium magnetite mainly exist in magnetite phase in the form of isomorphous substitution of iron [9,14,15]. Therefore, the key to releasing
the separation of vanadium-titanium magnetite and improves the TiO 2 recovery in ilmenite. Keywords HPGR, microcrack, vanadium-titanium magnetite, crushing process. Introduction Comminution (defined as crushing and grinding) accounts for the greatest proportion of the total energy consumed in a processing plant (Abdel-Zaher and Fuerstenau, 2009).
A new process comprising metallizing reduction, magnetic separation, and electroheat melting separation is proposed with the aim of achieving high recoveries of iron, vanadium, and titanium from vanadium titanomag-netite. The effects of magnetic intensity, reduction temperature, reduction
Coal-based reduction and magnetic separation behavior of low-grade vanadium-titanium magnetite pellets were studied in this paper. It is found that the metallization degree increased obviously with an increase in the temperature from 1100 °C to 1400 °C. The phase composition transformation was specifically analyzed with X-ray diffraction (XRD).
May 19, 2000 The photoinduced charge separation of methylphenothiazine in aluminophosphate type 5 and 11 (AlPO-5 and AlPO-11) containing Ti(TAPO-5, 11) and V(VAPO-5,11) is studied with near UV irradiation at room temperature. Methylphenothiazine cation radicals (PC1+) are produced in MAPO-5, 11(M = Ti4+ and V5+) molecular sieves, and characterized by electron spin resonance and diffuse
高达10%返现 Jan 19, 2018 Abstract. In recent years, a new process of “direct reduction-electric furnace smelting separation” has been put forward and developed for recovering the iron, vanadium, titanium and chromium to make full use of the chromium-bearing vanadium titanium magnetite.

Aug 23, 2016 Abstract. Slag dumping and water granulation are the most commonly used slag treatment methods in the metallurgical industries. In both processes, water is present (by desire for cooling and dispersion or as a result of rain accumulation) and thus equipment and operations are designed to minimize and mitigate the risk of steam explosions resulting from the inappropriate contact of slag with water.
高达10%返现 May 31, 2019 As a “wet” process, water granulation cannot recover high-grade waste heat from molten slags. The process consumes a large amount of water (about 1 ton of water per ton of slag is lost through evaporation) and may emit acid mist, H 2 S, and SO 2, causing serious air pollution. Furthermore, the wet granulated slag has to be dewatered at a
A method for treating a water slurry of granulated blast furnace slag containing particles of granulated slag having a size consist of about 0.635 centimeter × 0 (1/4 inch by 0) wherein a size separation of the particles is made at about 100 sieve. The sink fraction i.e. coarse particles larger than 100 mesh are partially dewatered and thermally dried prior to being comminuted with raw
• When slag is quenched with water, the high energy potential of the hot liquid slag is wasted (heating and evaporation of water. • For granulation, the circulated water has to be re-cooled in cooling towers or with other cooling methods. Mainly cooling towers are equipped with electrically powered fans and also the cooling water circulation
The present invention relates to a method for forming slag particles, whereby molten slag is converted into slag sand by a water jet and coarse slag using one or more conveying screws 4a mounted obliquely in the first settling tank 4c. The slag sand is discharged into the discharge plant 4 by withdrawing sand, supplying excess water from the first precipitation tank 4a to the second

A process for separation of the mineral components of a copper/molybdenum sulfide ore by flotation including (a) crushing and grinding the ore to liberate the minerals; (b) in a primary flotation circuit, adding a molybdenum collector selected from the group of hydrocarbon oils, and a frother; (c) floating a primary (molybdenum) concentrate in the primary circuit in the absence of a copper
Oct 27, 2020 Copper sulfide can be divided into single copper ore, copper sulfur ore, copper-molybdenum deposit, copper nickel, carrollite and so on. Basically, only flotation can be considered in its separation. Almost all copper sulphide ores contain iron-bearing sulfides, so in a sense, the flotation of copper sulfide is essentially the separation of
