Abstract
The invention discloses a physical beneficiation and phosphorus reduction method for skarn type high-phosphorus molybdenum ore, which comprises the following steps: (1) crushing: crushing and screening raw ores by a crusher, and returning and crushing the raw ores with the grain size of +3mm until the grain sizes of all the raw ores reach the grade of-3 mm; (2) grinding: adding crushed-3 mm raw ore into raw ore grinding equipment to perform closed circuit grinding operation, and simultaneously adding 500-1000 g/t of water glass and 250-800 g/t of phosphate rock inhibitor into a grinding machine to grind the raw ore to the content of 55-75% of-0.075 mm; (3) performing flotation roughing operation; (4) performing flotation scavenging operation; (5) regrinding the rough concentration molybdenum concentrate: adding 100-280 g/t of sulfur inhibitor and 150-300 g/t of phosphate rock inhibitor into the rough concentration molybdenum concentrate regrinding equipment to regrind the rough concentration molybdenum concentrate until the content of-0.045 mm is 70-95%; (6) and (5) flotation and fine selection operation. The method can reduce the phosphorus content in the molybdenum concentrate product to be below the standard, and obtain the high-quality molybdenum concentrate product.
Description
Technical field
The present invention relates to the beneficiation enrichment technology field of skarn type high phosphorus molybdenum ore, refer in particular to a kind of phosphorus falls in skarn type high phosphorus molybdenum ore method by physical upgrading, the high-quality molybdenum concntrate product that foreign matter of phosphor content is qualified can be obtained.The present invention is applicable to various skarn type high phosphorus molybdenum ore by the phosphorous high-quality molybdenum concntrate up to standard of physical upgrading explained hereafter.
Background technology
Molybdenum is a kind of silvery white rare metal, owing to having the advantages such as high strength, high-melting-point, corrosion-resistant, resistance to grinding, and be widely used in metallurgy, electrically, the industry such as chemical industry, Aero-Space, be non-renewable grand strategy resource, be developing high-tech, realize modernization of the country, build the important foundation material of modern national defense.Account for critical role in the whole nation, to economy, there is supporting role.
Molybdenum in China ore resources is very abundant, is one of large Dominant Mineral Resources of China six.The principle that China is poor, easy first and difficult later after usually following getting rich first to the exploitation of mineral resources, along with the high speed development of modern industry, the molybdenum ore resource of the molybdenum ore rich ore that China is limited and easily choosing is petered out, and current available molybdenum ore resource trends towards poor, thin, assorted day by day.In ore resource, S, P, Si etc. are referred to as objectionable impurities and the valuable mineral fine-grained disseminated grain of interstitial element, cause that ore dressing difficulty is large, efficiency is low, poor product quality.
Phosphorus in molybdenum ore mainly exists with the form such as apatite or fluor-apatite, mainly with granular and irregular aggregate, with tight symbiosis of gangue mineral such as target minreal molybdenite or calcite, pyroxene, garnets, should not with its Mineral separation, easily cause dressing product phosphorous higher.Because the molybdenum overwhelming majority is used for steel industry, as produce various steel alloy additive or with tungsten, nickel, cobalt, the senior alloy of the composition such as zirconium, titanium, vanadium, rhenium, and phosphorus is one of element very harmful in steel smelting process, phosphorus content increases, intensity, the hardness of steel improve, and plasticity and toughness significantly decline.Particularly temperature is lower, larger on the impact of plasticity and toughness, thus significantly strengthen cold brittleness and the solderability of steel, have a strong impact on the product quality of steel alloy, therefore metallurgical industry has strict demand to the objectionable impurities phosphorus in molybdenum concntrate product, and metallurgy industry standard (YS/T235-2007) requires impurity P≤0.02% in molybdenum concntrate product.
Because skarn type molybdenum ore can be molybdenum for the valuable element reclaimed, it is phosphorous, and to have height to have low, usual raw ore phosphorous more than 0.10% time, in the molybdenum concntrate that ore dressing plant is produced, objectionable impurities phosphorus often exceeds standard, and has a strong impact on selling price and the market of molybdenum concntrate product.The waterglass added in the floatation process of current ore dressing plant suppresses silicates gangue mineral effect better, if publication number is CN101380609, publication date is that the Chinese patent literature on March 11st, 2009 discloses the process suppressing phosphorus impurities in a kind of molybdenum concentrate floatation process, adopt and combine the regime of agent made up a prescription, waterglass, as pressing down phosphorus agent, to make an addition in molybdenum concentrate floatation primary grinding ball mill and to add with the ratio of 1.5-2 kg/tonne of raw ore by comprehensive use waterglass and prodan; Prodan is made an addition in molybdenum concentrate floatation secondary grinding ball mill by 20-30g/T raw ore, the impurity of molybdenum concntrate is effectively suppressed.
But phosphorous apatite mineral because disseminated grain size is comparatively thin, with the tight symbiosis of other mineral, waterglass class inhibitor is poor to its inhibition, causes it to be easily mixed in molybdenum concntrate, makes molybdenum concntrate foreign matter of phosphor content overproof, reduces concentrate molybdenum grade simultaneously.Strengthen waterglass consumption and might not reduce phosphorus content, but easily make molybdenum sulfide mineral produce groove phenomenon, reduce molybdenum recovery.For the phosphorous molybdenum concntrate product exceeded standard, molybdenum ore dressing plant adopts chemical mineral processing technique usually, in sour environment, namely adds special dephosphorization chemical agent, under about 110 DEG C conditions, carry out wet-leaching, to obtain the qualified molybdenum concntrate product of phosphorus content.This process costs is higher, and can produce poisonous and hazardous leaching waste liquid needs process, and the molybdenum of about 0.5% can be caused to lose simultaneously.
Summary of the invention
Thin for such skarn type high phosphorus molybdenum ore Phosphate minerals disseminated grain size, be difficult to be separated with the molybdenum-bearing mineral such as molybdenite, cause the phosphorous difficult problem exceeded standard of molybdenum concntrate product, the present invention proposes a kind of physical upgrading method for reducing phosphorus of skarn type high phosphorus molybdenum ore, adopt this method, under the prerequisite ensureing molybdenum concentrate grade and the rate of recovery, make in molybdenum concntrate product phosphorous be down to below the mark, eliminate ore dressing plant to exceed standard the subsequent chemistry dephosphorization operation that molybdenum concntrate carries out for phosphorus, reduce generation, economic benefit and the obvious environment benefit of production cost and waste liquid.
