Abstract: A multi-stage float sorting device includes a first flotator float-sorting ores mixed with water based on a difference in density, and a second flotator provided with a column extending in a top-down direction, one side of which communicates with the first flotator to receive primary concentrates, and float-sorts the primary concentrates based on a difference in density to obtain secondary concentrates. The second flotator includes a washing water jetting section provided at a top of the column to jet washing water, a gas sparger provided at a bottom of the column to jet an inert gas, and an opening and closing section located between the washing water jetting section and the gas sparger to partition an inside of the column into upper and lower regions, and form an opening for rising secondary concentrates in the column according to a pressure state of the lower region.

Abstract: The invention provides methods and compositions for improving a froth flotation type separation. The method uses a microemulsion to improve the effectiveness of a collector. The improvement allows for low dosages of collector to work as well as much greater amounts of non-microemulsified collector.

Abstract: Methods and compositions for separating materials are provided. In an embodiment, the present invention provides a method of separating a first material from a second material. For example, the method can comprise mixing the first material and the second material in a slurry with a beneficiation composition. The beneficiation composition can comprise one or more fatty acid by-products derived from a biodiesel manufacturing process. Air bubbles can be provided in the slurry to form bubble-particle aggregates with the first material and the bubble-particle aggregates can be allowed to be separated from the second material.

Abstract: A cement manufacturing apparatus capable of increasing quantity of fly ash used in the apparatus while controlling unburned carbon content in cement within a permissible range. The cement manufacturing apparatus comprises a removal means for removing unburned carbon from gypsum, and a grinding means for grinding gypsum from which unburned carbon is removed by the removal means together with clinker to generate cement. With the apparatus, total unburned carbon content in cement can be reduced, and the quantity of fly ash used in the apparatus can be, increased by the reduced amount of unburned carbon. The removal means can remove unburned carbon contained in gypsum as well as unburned carbon contained in fly ash, and the grinding means may grind the fly ash from which unburned carbon is removed together with the gypsum, from which unburned carbon is removed, and clinker.

Abstract: A method of producing enhanced coal combustion ash for use in pozzolanic applications or cement manufacture, in which the enhanced combustion ash has lower mercury content. A slurry is formed of the combustion ash and water and is subjected to froth flotation to form a mercury-enriched ash slurry and a mercury-depleted ash slurry. The product mercury-depleted ash slurry is isolated and may optionally be dried. The combustion ash may be pulverized prior to being used to form the slurry, reducing its mean particle size. The mercury-depleted combustion ash product has reduced levels of mercury and ammonia, and reduced particle size.
