Description
Technical field
The utility model relates to the Multifunctional mill floating lives of the ore grinding of ore and flotation, more particularly to complicated hard-processing copper sulfur ores
Producing line.
Background technique
Ore handled by Tongling Nonferrous Metals mine is mainly based on copper, sulphur ore.Copper mineral and sulfur mineral master in ore
To be partially the embedding cloth of coarse grain in, based on fine-grained disseminated grain, copper, sulfur mineral disseminated grain size are uneven, copper mineral disseminated grain size compared with
Carefully, sulfur mineral disseminated grain size is thicker, and part copper mineral is tightly combined with sulfur mineral.If grinding particle size is excessively thick, copper mineral cannot be single
Body dissociation, copper mineral recycling is not high, monomer dissociation is furthermore unable to the copper mineral of sulfur mineral adhesion, copper loss late mistake in iron concentrate
It is high.If grinding particle size is meticulous, increases ore grinding cost, while causing sulfur mineral overground, be difficult to inhibit in flotation, influence copper sulphur content
From.Property feature based on ore, original design are realized using mixed floating, middling regrinding and reprocessing the process flow of copper sulphur to copper sulphur
The recycling of mineral, design objective are raw ore cupric 0.7%, sulfur-bearing 11.0%；Copper concentrate cupric 15%, copper recovery 86.5%；Sulphur
Concentrate sulfur-bearing 35.0%, sulfur recovery rate 50.0%.
But with the exploitation in ore deep, raw ore copper, sulfur grade fluctuation are larger, and copper grade is in the range of 0.5-1.6%
Fluctuation, sulfur grade fluctuate in the range of 5-30%.When raw ore sulfur-bearing is lower, since design cycle is only in roughing operation pair
Sulfur mineral carries out a preenrichment, causes iron concentrate grade not high, 20% or so, iron concentrate is difficult to sell iron concentrate sulfur-bearing, makes
At the serious wasting of resources.When raw ore sulfur-bearing is higher, causes copper, sulphur bulk flotation time insufficient, lead to tailing copper, sulfur grade
Higher, copper sulphur loss late is larger；Simultaneously because copper, sulphur content from and the Regrinding floatation time it is insufficient, cause copper, sulphur content difficult, sulphur essence
Copper loss late is larger in mine, eventually leads to that Cu Concentrate Grade and the rate of recovery be not high, and iron concentrate is higher due to cupric, it is difficult to sell
It sells.
Chinese utility model patent notification number CN201300086 discloses the device for improving and regrinding system equipment running rate,
Bypass conduit is set up again at machine inlet pipe by regrinding in 1#, 2#, 3#, effectively the circulation of control slurry road, on the one hand give in this way
Faulty grinding machine again can also guarantee that the operating of other equipment is not affected with the sufficient repair time, improve
Operation rate, but the device can not fluctuation to sulfur content in raw material targetedly handled；For another example Chinese invention is special
Sharp publication number CN104209174A discloses a kind of Multifunctional mill and selects production line, prepares two ore mills, five flotation devices and one
The first valve, the is arranged with pipeline by two ore mills, five flotation devices and the connection of delivery pump in platform delivery pump on pipeline
Control switch is arranged in two valves, third valve, the 4th valve, the 5th valve, the 6th valve, the 7th valve and the 8th valve, the
One valve, third valve, the 5th valve, the 7th valve are serially connected in signal line road, the second valve, the 4th valve, the 6th
Valve, the 8th valve are serially connected in another signal line road, control switch not only connect with two bars line signals but also with it is each
Valve signal connection, enable normal work when between two bars routes the different workflow of switching control, needing
Can control the opening and closing of single valve when maintenance, but the mill select production line can not real-time judge when need to switch different stream out
Journey, that is to say, that switching time can not accurately be held.For another example Chinese invention patent publication number CN104646184B discloses one kind
Suitable for sorting the process of Copper making electroslag and vessel slag simultaneously, the mode of time sharing segment processing is taken, utilization is a set of
Equipment handles the process of two kinds of clinkers using different kinds of process flow, reduces production cost, the process and middle promulgated by the State Council
Bright patent publication No. CN104209174A is the same, and is carried out at time sharing segment to two different materials using a set of equipment
Reason, and two kinds of different material, that is, electroslags and vessel slag is almost constant containing copper grade.
Utility model content
The technical problems to be solved in the utility model is that existing raw ore treatment process can only be for different material with a set of
Equipment switches over different processes, but has ignored and go deep into mining, and the sulfur content in raw ore can change therewith, and then give
Treatment process brings adverse effect, is unfavorable for the separation and recycling of sulfur mineral and copper mineral, and the utility model provides complicated thus

Sound is very big, and existing procedure is difficult to adapt to the variation of ore properties.How to determine when that progress copper sulphur is mixed floating, middling regrinding and reprocessing
Process flow and the process flow for when carrying out the preferentially floating sulphur of floating copper, copper tail are a difficult points.The utility model is by multiple
Test, finds such a rule, as shown in Figure 1, three parts of raw ores of sampling test example 1-3 when sulfur grade in raw ore < 7%,
It was found that iron concentrate sulfur-bearing is 20% or so, iron concentrate is difficult to sell, and causes the serious wasting of resources, when in raw ore sulfur grade in 7%-
When between 18%, three parts of raw ore i.e. example 1-3 of test are sampled, find iron concentrate sulfur-bearing 35% or so, sulfur content occurs obviously
Variation；When sulfur grade in raw ore > 18%, three parts of raw ores i.e. example 1-3 of test are sampled, discovery iron concentrate sulfur-bearing is left 42%
The right side, but since raw ore sulfur-bearing is excessively high, it causes copper, sulphur bulk flotation time insufficient, causes tailing copper, sulfur grade higher, copper sulphur damage
Mistake rate is larger, at the same copper, sulphur content from and the Regrinding floatation time it is insufficient, cause copper, sulphur content difficult.Then the utility model, which is directed to, is somebody's turn to do
Characteristic devises a kind of mill floating life that can be monitored sulfur content in raw ore on-line and can switch corresponding process flow therewith and produces
Line grinds producing line of growing floating on water with the set and is able to detect that the variation of sulfur content in raw ore and cuts when it changes to key node 7%, 18%
Different process flows is changed to, qualified copper, iron concentrate product can be obtained, copper, sulphur sorting index are good.
