Description
Technical field
The invention belongs to technique of preparing field, relate to a kind of low grade potassium albite ore flotation impurity removal process.
Background technology
Gang's mineral that feldspar is made up of the aluminosilicate of potassium, sodium, calcium and barium, are modal ores in the earth's crust, and ratio reaches 60%, in igneous rock, metamorphic rock, sedimentary rock, all can occur.The fusing point of feldspar is between 1100-1300 ℃, and chemical stability is good, when with quartz and aluminosilicate congruent melting, has fluxing action, is often used to manufacture the auxiliary agent of glass and ceramic blank glaze, and can reduces firing temperature; In addition, the Vitrea generation of feldspar can also improve the light transmission of base substrate.
At present, potassium albite ore ore dressing removal of impurities is the technological process of conventional " ore grinding-desliming-magnetic separation-flotation " generally, first to ore pulverize, ore grinding, then carry out desliming operation and remove thin mud, adopt magnetic separator to remove impurity iron, finally enter floatation process, remove other impurity, obtain feldspar concentrate.Along with the lifting of the industry product quality requirements such as pottery, glass and chemical industry, high-precision potassium albite concentrate demand is increasing.And due to high-grade raw ore continually develop utilization, the feldspar ore of high-grade, Yi Caiyi choosing is petered out, be badly in need of a kind of new ore-dressing technique, can realize the potassium albite concentrate that floatingly selects high accuracy and high-recovery from complicated difficult choosing, low-grade feldspar raw ore.For this reason, (application number: 201110225768.5) disclose and a kind of processed the efficient ore dressing impurity removal process of potassium albite ore and combination medicament for complicated difficult, it is first in washup desliming, grind grading stage, desliming, regulates pH values of pulp to 8～10 to Chinese patent, in the alkaline flotation stage of reverse flotation removal of impurities, add saponification oleic acid (mass ratio of oleic acid and sodium carbonate is 1: 0.3～0.5) 1000～2000g/t+ benzene first hydroximic acid 1000～2000g/t for anion collecting flotation iron, titanium mineral, through dehydration after in the flotation in acidic condition stage, regulate pH values of pulp to 2～3, sodium chloride and potassium chloride 800～1500g/t are used for suppressing potassium albite, add cation-collecting agent lauryl amine and MIBC (methyl isobutyl carbinol) 200～400g/t after emulsification to be used for the impurity of flotation containing color, finally can obtain containing Fe2O3 and TiO2 content below 0.1%, Na2O and more than 14% feldspar concentrate of K2O content, directly firing whiteness can reach more than 55, can be used as superfine high-quality ceramic raw material, other products can be for baking bricks, and moisture stage backwater reuse used in technological process, be that water and the final acid tailings recycling water of sloughing after alkaline flotation can be distinguished Returning process reuse, comprehensive organic efficiency is high, and economical and practical, energy-conserving and environment-protective.But said method adopts the mode of segmentation reverse flotation removal of impurities in floatation process, alkalescence, flotation in acidic condition number of stages all act at 5 times, floatation process complexity, and floating agent use amount increases, and has increased production cost.
Summary of the invention
For the deficiencies in the prior art, the invention provides that a kind of technique is simple, production cost is low, can effectively improve the flotation impurity removal process of potassium albite recovery index, be particularly useful for complicated difficult choosing, low-grade potassium albite ore dressing field, realize the potassium albite concentrate that floatingly selects high-grade, high-recovery from low zinc grade raw ore, expand the utilization rate of mineral resources, to developing low-grade or secondary mineral resources is significant.
Concrete, technical scheme of the present invention is:
A kind of low grade potassium albite ore flotation impurity removal process, comprises that raw ore is chosen, ore grinding, desliming, magnetic separation and flotation operation, it is characterized in that, this technique concrete grammar step is as follows:
(1) corase grind ore deposit: potassium albite raw ore is carried out to fragmentation, ore grinding processing, control ore particle granularity and account for 70% for-0.045.
(2) magnetic separation removing impurities: adopt magnetic separator to carry out magnetic concentration working, flow rate of pulp is 0.8cm/s, and field intensity is 1.0T, and the impurity removing is done mine tailing processing.
(3) sedimentation desliming: the ore deposit raw material that step (2) magnetic separation is obtained is washed ore deposit, sedimentation desliming, the sedimentation time is 6min.
(4) fine grinding ore deposit: the ore deposit raw material that step (3) desliming is obtained carries out secondary grinding, controls ore particle granularity and accounts for 80% for-0.074.
(5) magnetic separation again: adopt magnetic separator to carry out magnetic concentration working again, flow rate of pulp is 0.9cm/s, and field intensity is 1.0T, further imurity-removal.
(6) flotation: adopt sulfuric acid as pH adjusting agent, controlling slurry pH is 2～4; Employing hydrofluoric acid is activator, and consumption is 30～50g/t raw ore, and employing sodium carbonate is dispersant, consumption is 40～60g/t raw ore, adopts lauryl amine as collecting agent, and consumption is 180～220g/t raw ore, adopt terpenic oil as foaming agent, consumption is 10～50g/t raw ore; Finally obtain potassium albite concentrate, process as mine tailing in residue ore deposit.
The constituent of feldspar ore mainly contains albite, potassic feldspar, mica mineral, quartz, calcite, also has a small amount of hematite-limonite.Iron content, calcium mineral are mainly distributed in fine fraction, and wherein iron is mainly composed and existed in biotite and hematite-limonite, and calcium is mainly composed and existed in calcite.Conventionally, iron-bearing mineral is mainly removed by high-gradient magnetic separation, and mica mineral is mainly removed by high-gradient magnetic separation and flotation, and calcite is mainly removed by desliming or flotation.
The present invention, by two ore grindings, two magnetic separation operation, further reduces ore particle granularity, can effectively remove iron-bearing mineral and mica mineral, reduces Fe in concentrate
2o
3content, put forward the quality of high potassium/sodium concentrate.By desliming operation, can effectively remove iron, the calcium mineral composed in existence-0.030mm fine fraction, reduce the difficulty that sorts of subsequent job.And mica mineral belongs to the silicate mineral of layer structure, in water, surperficial elecrtonegativity is very strong, and zero point is very low, adopt lauryl amine as collecting agent flotation, terpenic oil as foaming agent, effectively separating flotation goes out to be difficult to the mica mineral of removing, and isolates the impurity such as calcite, quartz simultaneously.
Processing step of the present invention is simple, and production cost is low, does not have problem of environmental pollution, has the positive effect of quick removal impurity, the high finished product rate of recovery, is suitable for industrial applications.
