摘要:
The present disclosure relates to an iron briquette produced by providing sponge iron pellets, providing carbon powder, producing a mixture of the sponge iron pellets and the carbon powder, and briquetting the mixture to provide an iron briquette comprising compressed sponge iron pellets and carbon powder located in interstitial spaces between the compressed sponge iron pellets, wherein the iron briquette comprises at least 0.2 wt% carbon powder, and wherein the sponge iron pellets comprise at least 0.5 wt% iron oxide and are essentially free of carbon. The disclosure further relates to a method for producing such an iron briquette.
摘要:
Disclosed is method of leaching at least one desired element from feed material containing feed material fines, which includes combining such a feed material with a pulping solution comprising a liquid and a solution-hydrated or a solution-soluble polymer to form a treated slurry, with the polymer configured to predominantly capture at least part of the feed material fines prior to their settling out of the liquid slurry matrix, and with the polymer being added to the feed material in a predetermined ratio of polymer to feed material. The treated slurry is deposited in a deposition cell for leaching and further treatment. Also disclosed is a composition of a treated slurry, and treating any one or more of the feed material, the treated slurry or the deposited treated slurry with sulphide consuming bacteria.
摘要:
The present disclosure provides a method of producing solid composites. The method comprises providing a bio-crude formed from the heat treatment of a carbonaceous feedstock comprising biomass. The bio-crude is capable of hardening at elevated temperature. The method further comprises mixing the bio-crude with a solid or paste to form a green composite and heating the green composite to produce a hardened solid composite.
摘要:
The application describes pellets comprising particulate iron ore and between 0.05 and 1.0% by weight of an organic binder. The use of such pellets in electric arc furnaces to produce steel is also described.
摘要:
Ein Formling mit den Hauptbestandteilen Kalkkomponente in Form von gebranntem Kalk, gebranntem Dolomit, Kalkstein und/oder Dolomitstein und Schwarzstoff in Form von Koks, Anthrazit und/oder Kohle und mit wenigstens einem als Brikettierhilfe wirksamen Hilfsstoff lässt sich stabil und einfach dadurch herstellen, dass die Kalkkomponente mit dem Schwarzstoff, der eine Norm-Partikelgröße zwischen 0 und 5 mm aufweist, sowie einem Zellulosefasermaterial zwischen 0,5 und 5 Gew.-% und einem Bindemittel mit einem Anteil zwischen 0,1 und 5 Gew.-% gemischt und anschließend zu dem Formling verpresst wird.
摘要:
Composition sous forme de briquettes crues ou cuites comprenant au moins un composé calco-magnésien vif comprenant et un composé à base de fer et son procédé d'obtention ainsi que ses utilisations.
摘要:
A composite product and a method of manufacturing the composite product are disclosed. The composite product includes (a) a polymeric material binder and a metal- bearing material or (b) the polymeric material binder and a carbon-bearing material. The 5 method includes heating and mixing the components of the composite product and thereafter forming the heated mixture into a final product shape, with the heating step being sufficient to melt at least a part of the polymeric material binder to facilitate forming the product.
摘要:
A sludge or slurry physical stabilizing method combines coarse particles with a slurry of fine particles to generate a composite slurry having a substantially predetermined ratio of coarse particles to fine particles. The composite slurry can then be diluted, flocculated and dewatered. Superabsorbent polymer (SAP) is mixed in with the dewatered composite slurry in an amount effective to produce a somewhat friable, semi-solid conveyable composition of sufficient strength to enable transport, stacking and support of restored overburden at a mining site.
