The invention relates to a beneficiation method for increasing the gold recovery rate of a gold ore tailing. A greenore is used as a carrier to connect the selected gold ore tailing to which beneficiation reagents are applied. The beneficiation method comprises the following process steps in order: a. ore pulverization: the greenore is pulverized; b. ore grinding: according to the proportion of 1 to 3 of the greenore and the selected gold ore tailing, the mixture of the selected gold ore tailing and the pulverized greenore to which the selected gold ore tailing is added is ground until the degree of fineness is minus 0.074mm and 60 to 76 percent; c. rough selection: 20 to 100g / t of butyl xanthate, 1 to 30 g / t of dithiophosphate BA and 5 to 20 g / t of No.2 oil are added to the finely ground mixed ore, and the mixture obtained is processed by the operation of rougher flotation; and d. fine selection: the roughly selected rough concentrate is finely selected by being added with 20 to 100g / t of sodium silicate so as to obtain gold concentrate selection. The beneficiation method has the advantages of high suitability of the processes, easy procedure and operation, no pollution, environmental friendliness, low production cost, high recovery ratio, etc.

The present invention provides a ft synthesis reaction process based on the fixed bed reactor is that the cycling medium enters from the top of the fixed bed reactor after preheated, the feed gas formed by mixing the syngas with the tail gas enters from the lower of the fixed bed reactor to contact with the catalyst to process ft synthesis, the product is fully collected to process the separation of water, a long chain hydrocarbon and a gas phase component; the long chain hydrocarbon processes C5-C18 middle distillate, the separation of C18+hydrocarbon and gaseous low carbon hydrocarbon, one part C5-C18 middle distillate is mixed with the cycling liquid medium, the other part is processed oil product process, C18+hydrocarbon fully enters in the oil product process, the gaseous low carbonhydrocarbon mixing with the gas phase component forms the tail gas, the water component is used as a gas agent to return in the gasification system. The invention has high heat exchange efficiency, high syngas throughput, lower cycling gas quantity, lower energy consumption, stable operation.

The invention relates to a method for preparing calcium sulfate crystal whiskers (CaSO4) by using impurity-containing gypsum as a raw material. The method comprises the following steps of: removing main impurities in the raw material which is the low-priced impurity-containing gypsum resource in a mode of roasting, acid-complex leaching and alkaline leaching and simultaneously thinning crystal grains to obtain a superfine dihydrate calcium sulfate precursor which is high in purity and dispersibility; and preparing the anhydrous calcium sulfate crystal whiskers with a length of 20 to 2,000mu m, a diameter of 0.5 to 20 mu m, a length-diameter ratio of 40 to 1,000 and a weight percent content of over 95 percent in a mode of hydrothermal conversion-roasting of a fluxing agent. The method has the advantages of low-priced and easily bought raw materials, simple process, wide application range, and high added value. The calcium sulfate crystal whiskers prepared by the method have a big length-diameter ratio and regular shape, and can be used as reinforcing, heat insulating or flame retardant materials in industries of plastics, rubbers, coatings, papermaking, building materials and the like.
