Принадлежит: Tata Steel Ltd

A method for separating particles of different specific gravity from a sized ore feed, wherein the ore can be coal, metallic, non-metallic and mineral ores. The method particles from the ore are sieved to obtain size fractions of different particle size ranges, after which a load of particles of a size fraction are placed in a container and fluidized by passing a fluid flow through the load of particles. By lowering the flow velocity of the fluid through the load the particles are deposited in the container in one or more layers depending on the specific gravity of each of the particles, after which the deposited particles are separated in portions of different specific gravity. The portions represent different ore content of the particles in each portion on basis of which the theoretical yield of the ore can be determined. The invention provides an apparatus to carry out the method.

GREEN METHOD FOR PRODUCING A MIXTURE OF MULTIPLE NANO-CARBON POLYMORPHS FROM COAL

Номер: US20220048771A1
Автор: LAU Leo Woon Ming, SHAN Aixian
Принадлежит:

The present disclosure relates to a green method for producing and exploiting multiple nano-carbon polymorphs from coal commonly known as anthracite, meta-anthracite, and semi-graphite. The method disrupts the prevalent environmentally unfriendly practices of burning coal with poor profitability and sustainability because the method yields an unexpectedly rich mixture of high-performance nano-materials, comprising carbon nano-fibers, carbon nano-tubes, carbon nano-onions, nano-graphite-plates, and nano-graphene-disks, by simply mechanically-comminuting coal to nano-size, with minimal sorting efforts. The resulting total-yield of nano-carbon polymorphs is over 50% by weight from properly selected coal. Innovative means are added to the prevalent comminution and sorting practices to further reduce energy and chemical consumption. More importantly, the method also refines the comminution and sorting details for producing the best custom-made formulations. This holistic engineering approach eliminates unnecessary separation and sorting steps because a custom-made formulation typically requires blending the sorted components. Formulations with mixed nano-carbon polymorphs are engineered as new and high-valued-added composite ingredients to critically raise the performance of cement-based, polymer-based, and metal-based composites. 1. A method for extracting from coal more than one nano-carbon polymorphs , wherein the method uses no oxidation nor any chemical etch but uses environmentally friendly processes comprising:the selection of a proper coal source;dry mechanical pulverization of the selected coal;float-sink separation of organic constituents from inorganic mineral constituents;wet-comminution of the separated organic constituents to 200-1000 nm with no grinding grit;follow-up wet-comminution of the sub-micron comminuted organic constituents, with the assistance of grinding agents, to yield nano-carbon polymorphs smaller than-100 nm;sorting of multiple nano-carbon ...

A waste management system, primarily intended to be for waste floating in water, though it can also be used on land. A shredding device will reduce the size of the particles of waste. Ocean water is removed by a drying device. The dried waste material is cryogenically frozen using liquid nitrogen or other suitable means. The frozen waste material is then pulverized and ground into a powder. The powder may then be sprayed into a gas-filled chamber and heated. Temperature, pressure and humidity are maintained within the chamber for more than one minute. Microwave or other radiation and catalysts may be used to enhance the process of extraction. The processed material is then removed from the chamber. Carbon and water may be recycled. The carbon may be used as fuel by the ship. Water may also be used by the ship or returned to the ocean in a non-toxic condition.

Disclosed is an underground coal preparation process adopting a water medium, comprising: feeding exploited raw coal into a Φ25 mm raw coal classifying screen for screening; performing dry coal preparation on a classifying screen oversize product with a particle size greater than 25 mm and feeding a classifying screen undersize product with a particle size less than 25 mm into a special underground compact jigging machine for sorting to obtain jigging machine overflow clean coal, jigging middling coal and jigging gangue; screening and dewatering the jigging machine overflow clean coal to obtain a clean coal product, and screening and dewatering the jigging middling coal to obtain a middling coal product, sorting slime water to be sorted and generated during sorting to obtain coarse clean coal slime and coarse middling coal slime, and performing circulating water treatment on a final liquid. 1. An underground coal separation process adopting a water medium , comprising following steps:feeding an exploited raw coal into a Φ25 mm raw coal classifying screen by a raw coal feeding chute T for screening to obtain a classifying screen oversize product with a particle size greater than 25 mm and a classifying screen undersize product with a particle size less than 25 mm;feeding the classifying screen oversize product with a particle size greater than 25 mm into a TDS intelligent dry separator to perform a dry coal preparation, and separating to respectively obtain a dry separation clean coal and a dry separation gangue to be discharged;feeding the classifying screen undersize product with a particle size less than 25 mm into a special underground compact jigging machine for separation to obtain a jigging machine overflow clean coal, a jigging middling coal and a jigging gangue, and directly discharging the jigging gangue; due to a high water content of the jigging machine overflow clean coal, feeding the jigging machine overflow clean coal into a fixed screen for ...
