Definitions
- the present invention deals with a process for producing high purity synthetic magnetite from wüstite.
- the invention relates to a process of oxidation of powdered wüstite with superheated water vapor to convert it into high ureza magnetite » where wüstite is oxidized in a reactor with a countercurrent or concurrent steam flow, during a certain time and at a temperature such that they allow oxidation; total wüstita in magnetite,
- magnetite, 40 4 there are several known processes for obtaining magnetite, 40 4 , from hematite, Fe 2 0.i.
- the conversion of hematite eii magnetite is carried out by means of a chemical reduction.
- the reducing agents commonly used for this process are hydrogen gas, carbon dioxide, methane gas, propane gas, ethane gas, etc.
- the invention consists of a process for producing magnetite with a purity of not less than 90%, and exceeding 98%, by oxidation of powdered wüstite (iron oxide), under temperatures from 200 * C to 800 "C, with introduction of liquid or vapor-shaped water, countercurrently or concurrently, in a reactor with externally heated controlled atmosphere,
- the amount of water used to oxidize wüstita is 60 to 500 mi per kilogram of wüstita, grains of dust wüstita Introduced to the reactor is no larger than 100 ⁇ .
- the present invention consists of a method for converting synthetic wüstita cri magnetite of high purity. Specifically, the invention describes a process that consists of the oxidation of wüstite in a reactor subjected to high temperatures and with a controlled atmosphere with a water flow, or a flow of water vapor in a countercurrent or concurrent way, during a time established to allow the Total reaction of wüstita and its conversion and magnetite.
- the invention contemplates the design of a reactor which, when heated, conforms to e (set of this invention. The reaction is expressed in the following equation:
- hematite is a reddish brown iron ore obtained as a byproduct of the hydrochloric acid regeneration operation used in the pickling or cleaning of steel wires in processes such as electroplating, From these levels it has traditionally been obtained iron, widely used in industry.
- the synthetic magnetite obtained from this process is used for its magnetic properties or as a pigment.
- a reducing medium such as hydrogen, carbon monoxide, methane gas or a liquid such as petroleum.
- monoxide gas, petroleum liquid, methane gas or natural gas acts as a reducing agent . of the hematite allowing the reduction to magnetite. See US Pat. 5,348,160, US,. : 5749,791. '
- the scale is generally stacked or deposited in large pits with other metallic or non-metallic waste or with electric furnace scorpions. This requires the adaptation of land for this purpose but does not prevent the permanent and indefinite accumulation of this waste since there is no suitable recycling method so far, E the country produces 80,000 tons of steel monthly in the three main steelmakers, what we; It leads to a production of 1, 600 to 2,400 tons of husks per month, which accumulate and can become a real environmental problem.
