Abstract
The method that the wollastonite sorting is purified adopts single method for floating emersion calcite, garnet, diopside, quartz successively.With aluminum soluble salt or molysite is activating agent, and oxysalt is made collecting agent float stone garnet.With soluble copper salt or lead salt is activator, and oxysalt is made the floating diopside of collecting agent.The same conventional program of each flotation circuit program.Adopt that this method flow process is simple, small investment, cost be low, garnet, diopside removal efficiency＞90%, Fe in the concentrate
2O
3Content＜0.5%, concentrate grade reaches 85%-90%.
Description
The invention belongs to the ore-dressing technique class, belong to the ore-dressing technique class of wollastonite particularly.
In the wollastonite, its valuable mineral is a wollastonite.Gangue mineral also contains weak magnetic mineral garnet and diopside except that containing calcite, quartz." non-metallic mineral industry handbook (in December, 1992 P1113-1114 of metallurgical publishing house) has summed up the main beneficiation method and the main ore-dressing technique principle process of wollastonite according to the research and the practice of wollastonite ore dressing both at home and abroad.From wherein as seen, wollastonite, with garnet, diopside separates needs to adopt magnetic selection method.So for both containing garnet, diopside contains calcite again, quartzy wollastonite mine has only employing magnetic separation-flotation or flotation-magnetic separation combined process flow, just can obtain high-grade, low impurity (Fe
2O
3) concentrate, to satisfy every production needs.
Magnetic separation-flotation-or flotation-magnetic separation also has magnetic separation-flotation-magnetic separation combined process flow to have technological process complexity, equipment price costliness, problems such as equipment configuration difficulty, investment are big, beneficiation cost height, thereby provide new beneficiation method necessary.
The objective of the invention is according to above-mentionedly contain garnet, diopside, calcite, quartzy wollastonite must be taked combined process flow, and there is the situation of the problems referred to above again in combined process flow, is intended to design a kind ofly utilize single flotation process to carry out the method that sorting is purified.The technological process of employing this method is simple, investment is little, beneficiation cost is low.The concentrate grade that adopts this method to purify is 85-90%, Fe
2O
3Content＜0.5%.
The objective of the invention is to realize in the following manner, the method that the wollastonite sorting is purified is that adjustment agent, oxidized paraffin wax soap are made collecting agent, the emersion calcite with sodium carbonate.Use amine collector emersion quartz.Garnet, diopside are also taked the method for floating emersion, and its mineral floating is in proper order: floating calcite, float stone garnet, floating diopside, float stone English get the wollastonite concentrate.With aluminum soluble salt or molysite is activator, and hydrocarbon an aromatic plant metioned in ancient books oxysalt is a collecting agent, the emersion garnet.With soluble copper salt or lead salt is activator, and hydrocarbon an aromatic plant metioned in ancient books oxysalt is a collecting agent, the emersion diopside.
Accompanying drawing is a flotation principle flow chart of the present invention
With reference to accompanying drawing, the present invention adopts single method for floating to the wollastonite raw ore behind ore grinding, and emersion side separates successively Get the wollastonite concentrate behind stone, garnet, diopside, the quartz. In each flotation circuit, the amount of required flotation agent is generally decided according to content and the distribution characteristics thereof of each component in the raw ore, and the consumption of medicament is as shown in table 1 in the present invention.
Table 1
| The flotation circuit title | Floating agent | Dosing (gram/ton) |

| Quartzy flotation circuit | Amine collector | 10－300 |
Annotate: when the content of soluble aluminum salt or molysite in the wollastonite can reach activate request, then in the garnet flotation circuit, can not add activator, and directly add collecting agent, so the time activator dosage be 0.
Adopt the present invention, the same conventional program of each flotation circuit program, just behind the emersion calcite, adjusting ore pulp PH is 6-9, adds activator aluminum soluble salt or molysite, collecting agent oxysalt, emersion garnet in ore pulp.Adjusting ore pulp PH again is 5-8, adds activator soluble copper salt or lead salt in ore pulp, collecting agent oxysalt, emersion diopside, last emersion quartz.After above-mentioned flotation, garnet, the diopside removal efficiency can be greater than 90%, Fe in the wollastonite concentrate
2O
3Content be reduced to below 0.5%, concentrate grade reaches 85%-90%.
The present invention contains calcite again to both containing garnet, diopside, and quartzy wollastonite mine adopts single method for floating, and by ore dressing order FLOTATION SEPARATION successively, technological process is simple, investment is little, beneficiation cost is low.For the wollastonite ore dressing plant of building equal scale, adopt the present invention to reduce 20-25% than conventional magnetic, floating flow process building equipment investment, beneficiation cost reduces 5-10%.
Enumerate the embodiment of the invention below:
Hubei wollastonite mine (NO1), Hubei copper mine (NO2, NO3) adopts the inventive method that wollastonite mine is carried out sorting respectively and purifies, raw ore mineral composition content % sees Table 2, garnet, diopside floating agent consumption (g/ ton) see Table 3, the float test mode of being taked sees Table 4, and flotation results sees Table 5.
Table 2
Table 3
Annotate: Fe in the NO2 raw ore
2O
3The content height, wherein the soluble iron salt content reaches activate request, so the activator dosage is 0.
