Abstract
The present invention discloses process of extracting feldspar concentrate from giant-grained granite. The process includes the steps of ore dressing and grading, milling and grading, gravity separating and magnetically separating. The product has Fe2O3 content below 0.09 %, and K2O Na2O content raised from 6.6 % to 12.37 %. The present invention has waste granite utilized, saving in resource and environment friendship.
Description
Technical field
The present invention relates to a kind of method of extracting feldspar mineral concentrate from giant grainte waste stone, a kind of process of from the giant granite barren rock, extracting feldspar concentrate that relates to of saying so specifically.
Background technology
CN1151894C discloses a kind of " extracting method of potassium feldspar mineral material ", gets with sieve that potassic feldspar mineral (phenocryst) are raw material in the weathered granite, through the friction washup mineral is purified, the sieve decontamination pulverizes after low intensity magnetic separation precipitates dry, make raw mineral materials, its K
2O content height, K
2O: Na
2O is greater than 3, Fe
2O
3Content is less than 0.13-0.3%.
The conventional production process of present feldspar, be to select high-quality feldspar ore deposit directly to use or adopt broken ore grinding and easy removal of impurity purifying technique, natural high-quality feldspar mineral resources is limited, to removal of impurities purifying technique common or that low quality feldspar mineral are used always, as the beneficiation method of flotation, magnetic separation, flotation+magnetic separation, generally control the Fe of feldspar concentrate
2O
3Content has just satisfied the requirement of primes less than 0.3%.
Along with development in science and technology and social demand increase, high-quality feldspar product-use has obtained further expansion, both at home and abroad industries such as pottery, building materials, efficient material to the feldspar goods not only demand increase considerably, and requirement is higher on quality, Fe
2O
3The height of content has just become the bottleneck of feldspar product property height.
Summary of the invention
The present invention aims to provide a kind of method of utilizing extracting feldspar mineral concentrate from giant grainte waste stone, makes full use of the giant granite barren rock and extracts Fe
2O
3The feldspar concentrate that content is extremely low is to satisfy the application requirements of industries such as pottery, building materials, efficient material.
To achieve these goals, the method for extracting feldspar mineral concentrate from giant grainte waste stone of the present invention is, the washup classification, and the giant granite stone in the water flushing probability screen screens out mica, quartz and clay, reaches the purpose that iron falls in silica removal, and it is rough to obtain feldspar; The frosted classification stops in ball mill feldspar is rough, adds the water mill ore deposit, making fineness is 250 purpose ore pulps, through spiral classifier, makes ore pulp insert high frequency fine screen, realize separating of feldspar mineral and phlogopite, biotite, clay mineral, make the grade ore pulp that meets the ore dressing requirement; Gravity treatment places hydrocyclone with ore pulp, and phlogopite, biotite, clay mineral in the feldspar mineral are further separated, and improves the purity of feldspar, makes the feldspar rough concentrate; Magnetic separation, magnetic magnetic separation (6000-9000GS) at first adopting is carried out deironing to the feldspar rough concentrate, remove mechanical iron, magnetic iron ore, feldspar is further purified, adopt high-gradient magnetic separation (1.2-1.6T) then, the feldspar rough concentrate is carried out deironing, remove bloodstone, siderite, make Fe
2O
3Content below 0.09%, K
2O and Na
2O content is from 6.16% feldspar concentrate of bringing up to more than 12.37%.
The present invention compared with prior art has following advantage:.
Adopt weight---magnetic combined mineral dressing technology, make the Fe of giant granite barren rock
2O
3Content is reduced to below 0.09% from 3-5%, made high-quality feldspar concentrate, has satisfied in pottery, building materials, the efficient manufacture of materials requirement to feldspar.
The giant granite barren rock can only be done construction material usually, and the feldspar mineral resources is also very short, and the present invention becomes barren rock into the high-quality feldspar concentrate, has not only obtained economic worth preferably, also has significant social and environmental benefit.
Description of drawings
Fig. 1 is a craft block-diagram of the present invention.
The specific embodiment
The present invention is described in further detail below in conjunction with accompanying drawing.
Technology shown in Figure 1 through washup classification, grind grading, gravity treatment, magnetic separation, makes feldspar concentrate.
One) washup classification: the giant granite barren rock is placed in the probability screen, and the water flushing screens out quartz, mica, clay, reaches the purpose that iron falls in silica removal, and feldspar is separated, and it is rough to make feldspar.
Two) grind grading: use the wet type continuous ball mill, adopt metal backing and steel ball to make ball-milling medium, with the rough ball mill that places of feldspar, add the water mill ore deposit, making fineness is 150 purpose ore pulps, through spiral classifier, make ore pulp place high frequency fine screen, realize feldspar mineral and phlogopite, the further separation of biotite, clay mineral, the ore pulp grade that makes meets the ore dressing requirement.
Three) gravity treatment: utilize the difference of mineral sinking speed in the ore pulp behind the grind grading, ore pulp is placed hydrocyclone, make feldspar and phlogopite, biotite, clay mineral high separation, realize the purpose of purification feldspar, make the feldspar rough concentrate.
Four) magnetic separation: magnetic preliminary election 1), adopt the magnetic separator of 6000-9000GS that the feldspar rough concentrate is carried out deironing, remove ferromagnetism iron tramps such as mechanical iron, magnetic iron ore, the purification feldspar; 2) high terraced high intensity magnetic separation, the high gradient magnetic separator of employing 1.2-1.6T carries out further deironing to the feldspar rough concentrate, removes weak magnetism impurity such as bloodstone, siderite, makes Fe
2O
3The feldspar concentrate of content below 0.09%.
