Vibrating feeder is the first part machine in rock crushing plant. With the help of vibrating feeder, it will improve the feeding speed and working efficiency for clients. Based on this characteristic, the vibrating feeder for sale will be suitable in mineral ore mining production line, building material, chemical industry and so on. Vibrating feeder can send materials to crusher evenly and continuously. Used in Nigeria rock production line, the vibrating feeder will take the raw materials into the primary crusher machine. It features smooth vibrating, reliable operation and long service life.
In small scale gold ore mining plant, crushing and grinding machines are used as the main machines. For example, crushing machines can be divided into jaw crusher, impact crusher, vertical impact crusher, hydraulic cone crusher, hammer crusher, and mobile crusher and so on. They have various types in practice.
It must be understood that the above specific example of processing fluorite is given only as an illustration of the process of the invention and is not to be interpreted as limiting the process of the invention to any specific number of dry centrifugal impact grinding mills nor to any specific peripheral speeds at which the rotors in the dry centrifugal impact grinding mills are operated since all ores have different fracture characteristics which will determine the number of dry centrifugal impact grinding mills needed and the varying speeds at which the rotors must be operated in order to obtain comminution of the ores and liberation of minerals from gangue at a specific liberation size to produce a predetermined grade of concentrate of the particular mineral which is being processed. The fracture characteristics of ores can be determined on a laboratory basis prior to comminution by the process described herein.
For solving the problems of the technologies described above; The technical scheme that the present invention proposes is a kind of method of utilizing desert drift-sand ore dressing to prepare the Feldspar Powder concentrate; This method comprises early stage deferrization process, mid-term feldspar floatation separation process and later stage deferrization process; Said early stage, deferrization process specifically may further comprise the steps: at first the desert drift-sand is carried out dry type magnetic separation and separate, the concentrate after dry type magnetic separation is separated carries out gravity treatment to be separated, and the concentrate after gravity treatment is separated carries out brute force scouring, graded desliming; Carrying out wet magnetic separation then separates; Obtain removing iron ore concentrate at last and be used for feldspar floatation separation process in mid-term, the feldspar mineral aggregate that obtain behind the feldspar floatation separation process mid-term passes through the later stage deferrization process again, prepares the Feldspar Powder concentrate.
) collecting ability, to pyrite and oxidized ore collecting ability a little less than; And nonyl hydroximic acid facile hydrolysis is NH2OH and carboxylic acid, energy and Cu2+Ion generates compound, and is strong to the cupric oxide ore collecting ability, inoperative to gangue minerals such as calcite, quartz.Among the present invention, the copper flotation collector is amyl group xanthic acid Ethyl formate C5H11OCSSCOOC2H5With nonyl hydroximic acid (C9H19) CO (NHOH).Amyl group xanthic acid Ethyl formate is strong to copper sulfide mineral (comprising primary chalcopyrite and secondary vitreous copper, copper orchid etc.
A marked decline in production has taken place in the Almeria region because values reached 51 kt in 2008. Other deposits have been important in the Calatayud Basin (Zaragoza), although since 2011 they have been inactive .In Spain, there is active exploitation of bentonites in three areas: (i) the Tajo basin (Madrid–Toledo provinces), which is located in the center of the Iberian Peninsula; (ii) Tamame de Sayago (Zamora province), which is 250 km to the northwest of Madrid and is associated with a deposit of kaolin; and (iii) the Cabo de Gata volcanic area (Almeria province) in the southern part of Spain. The values of production in 2016 were 142 kt in the Tajo basin, 10 kt in Tamame de Sayago, and 3 kt in the Cabo de Gata volcanic area, although production in Tamame de Sayago has increased notably in the last few years.
