Abstract: The present disclosure provides a method of preparing a composition of a cold setting geo-polymer based building material. The cold-setting geo-polymer concrete is a green concrete that requires curing at ambient conditions. The method includes mixing one or more aggregates and a plurality of chemical ingredients in a mixing apparatus, and chemically activating an obtained geo-polymer concrete mix by adding an alkaline activator. The one or more aggregates include a plurality of stone chips and a plurality of sand particles. The plurality of chemical ingredients includes a fly ash and a calcium hydroxide solution. The fly ash includes one or more alumino-silicate aggregates. The fly ash, the plurality of sand particles and the calcium hydroxide solution, and the plurality of stone chips are mixed in a first pre-determined ratio. The alkaline activator prevents temperature curing of the cold-setting geo-polymer concrete.

Abstract: The present disclosure provides a beneficiation arrangement for removing silica from an ore. The beneficiation arrangement includes one or more scrubbing arrangements to scrub the ore with a stream of a washing fluid and recover the silica, one or more screening arrangements to perform screening of the scrubbed ore to extract a first quantity of recovered ore and an underflow, and one or more separating arrangements to enable separation of at least silica particles from the underflow. The one or more separating arrangements include one or more cyclonic separating arrangements to cyclonically separate the silica particles into one or more ranges of sizes of the silica particles from the underflow, and one or more filter press arrangements to perform pressure filtration on a recovered ore extract mix of the one or more recovered ore extract mix.

Abstract: The present invention provides a method and system for extracting a plurality of red mud lumps from a slurry. The method and system includes separating an aqueous content from the slurry by simultaneous action of one or more de-watering agents and a physical force, and extracting the plurality of red-mud lumps having a moisture content of less than 18 percent from a slurry mixture. The separating of the aqueous content from the slurry includes feeding the slurry mixture to a filtering arrangement, exerting a first physical force to the slurry mixture in the filtering arrangement; and exerting a second physical force to the slurry mixture in the filtering arrangement. The slurry mixture includes the slurry and the one or more de-watering agents in a pre-determined quantity. The filtering arrangement is utilized for the extracting of the plurality of red-mud lumps from the slurry.
