The structure of sand storage silo for the use of coarse sand cemented fill and its pulp discharge method have been studied in this paper. A new type of sand storage silo with local fluidization and siphon discharging is recommended. The tests proved that the flow rate and the density of pulp discharged from this silo are stable during the operation. The solid's concentration is approximate to 67%~72% by weight.The method for calculating fluidization parameters, flow rate and effective pressure of this...

China is known for its richness in metallic ore resources with almost all varie-ties,having a long history of mining activities.Throughput has been constantly incre-asing,while technology improving.Despite of the raw ore grade decreasing,recoveries of main metals have beenraising and kinds as well as the output of by-products expanding.The present paperdescribes the progress in grinding,classification and in the beneficiation of tungsten,tin,complex sulphides,copper,molybdenum,nickel,precious metals and iron ores.GRINDING AND CLASSIFICATION Autogenous and semi-autogenous mills havebeen increasingly used,especially in iron concentrators.In some plants,magneticpulleies are used to discard wastes from autogenous mill discharges.Comparing withball mills,the consumption of grinding media has been reduced by 40% in plant usingrod-pebble mills.The fine screening with rappers has been widely adopted in magnetiteplants for upgrading concentrates.In some plants,hydrocyclones have been replacedby F.S.R.unites as classifiers.TUNGSTEN AND TIN Although multistage grinding and gravity separation aremainly applied to the beneficiation of such ores,combined flowsheets of gravity,magnetic separstion and flotation are also used.In the treatment of ore slimes,gravitymethod with centifugal separators for roughing followed by vanners for cleaning issuccessfully adopted;flotation and combined processes of gravity separation and flota-tion have been increasingly used;rock-shaking vanners are also introduced.Progress,in the concentration of tungsten ore slime,has been made by way of high intensitymagnetic separation followed by flotation.The methods of cleaning rougher concentra-tes comprise gravity,magnetic,electrostatic separation,table flotation and flotation aswell as combined processes of beneficiation and metallurgy.Some concentrators treatingrefractory cassiterite ores produce,in addition to final tin concentrates,low gradesemi-products for further treatment with special metallurgical processes.COMPLEX SULPHIDES In respect of the methods of separation,many a cyanide-free and dichromate-free separation methods have been developed,resulting in impro-vements of separation efficiency;reduction of environmental pollution and increasingrecovery of precious metals;and solution of the problems associated with separationof some complex sulphide ores,containing a large amount of secondary copper mine-rals.In addition,the electroflotation technique has been introduced in a lead-zincconcentrator,resulting in saving regulators and depressors.As concerns the flotationflowsheet,“equi-flotability” has been widely used. COPPER A number of effective flotation reagents have been utilized.Flotationcolumns have been used for more than 20 years,and a new type annular-ejectingflotation machine has also been put into operation.With respect to the recovery ofrefractory oxidized ores,both the single stage segregation with direct heatingand the leaching-extraction-electrowinning processes are in operation.Some othermethods have also been investigated with better results,such as,pressure ammoniacalleaching,pressure ammoniacal leaching with sulphur precipitation-flotation,pressuresulphidization-flotation and leaching-precipitation-carrier flotation.MOLYBDENUM,NICKEL AND PRECIOUS METALS The flotation flowsheet ofmolybdenite trends towards open circuit,i.e.discarding final tailings in cleaningstages.Furthermore,some concentrators also produce middlings for further treatmentwith hydrometallurgy.Heavier wax and combined collectors are adopted in someconcentrators,improving molybdenum recoveries.In a certain plant dealing with difficult nickel ores,flotation-desliming-magneticseparation-flotation flowsheet has been used instead of single flotation.Recoveringcobalt alloy from converter slags and separating richer precious metal alloy fromnickel matt with ore dressing methods have been put into practice.Extracting gold with thiourea has been investigated in commercial scale test withbetter results achieved.Recovering precious metals from anode slime and leachingresidues

In this paper a study of Reynolds number of the two phases flow has been carriedon a spiral sluice and a pinched sluice as representatives of gravitation concentrationseparators for fine particles processing.Relative physical quantities concerning thecalculation of Reynolds number such as flow rate,percentage solid,pulp density,pulpviscosity,and flow thickness as well were once measured by various devices,Reynoldsnumber of two phases flow was calculated respectively.The distribution role of Re,i.e.The distribution role of flow form was revealed.As far as spiral sluice is conce-rned,the distribution of Reynolds number along its radial direction may be dividedinto three zones,namely,lamina zone,turbulent zone and transitional zone.Theseparation zone of spiral sluice is found in the transitional zone.For pinched sluiceis however that the Re distribution along its thickness is as turbulent zone near itssurface layer,lamina zone is lacated at its bottom layer,the main separation zonemay appear in the surface layer.After a determination of the flow form was made,forces applied on the particles within the main separation zone were analyzed.To theauthors opinion,it is considered that the force inducing the particles kept at suspensionand loose state in that zone is principally of a dispersing pressure of shearing action.Based on the analysis of forces,a lower limit of particle size recoverable was calcu-lated.It clearly shows that a study of Re of two phases flow can give a rise to sepa-ration mechanism.It may also be considered that to mantain Re distribution underproper control is ore of the optimal separation conditions,and also provides a newroute for designing a new type of surface of a separation table.Meanwhile,flow form of two phases flow was investigated,the test results confo-rmed that Re 300 can also be taken as a criterion for this particular flow.

本文以螺旋溜槽、尖缩溜槽为代表的细粒重选设备进行了两相流雷诺数的研究。采用各种测试手段对计算雷诺数相关的物理量——流速、浓度、密度、粘度、流膜厚度进行测定,然后分别计算两相流雷诺数,查明分选过程雷诺数的分布规律,揭示流膜的特性及分选机理。同时还考查了两相流流态的判定标准,表明仍可借用 R_e=300作为判别标准。
