Nickel minerals and the openpit for vulcanizing cupro-nickel associated minerals change when doing Tailings Dam, improved Tailings Dam production technology.
Background technique
In bargh, tcrude ore enters useful mine of the dressing plant after broken, ore grinding and sorting operation, in ore
Object sorting is one or more concentrate products, and a large amount of useless mineral (tailing) are then with the discharge of ore pulp state.In order to comprehensively utilize
The pollution of mineral resources and elimination to environment, it is necessary to adopt an effective measure and tailing is handled.In general, the heap of mill tailings
The mode of depositing has dry piling and wet type to store up two kinds, and China's overwhelming majority mill tailings all use wet type stacked arrangement.
Tailings Dam be store up tailing place, mostly by dykes and dams and mountain valley enclose cut form.Conventional Tailings Dam is according to orographic condition
And construction method can be divided into mountain valley-type, hillside type, flat type；By model split of building a dam, type (including barren rock of once building a dam can be divided into
Build a dam) and two kinds of tailing heap dam type.The building and use of conventional Tailings Dam are the technologies of a comparative maturity, but land occupation is larger,
And it also will cause certain influence to environment, destroy vegetation and arable land.Use what surface mining left to adopt hole as Tailings Dam
It is a kind of novel stacked arrangement of conventional Tailings Dam, Tailings Dam construction cost is few, and does not generate secondary pollution to environment.
In terms of open-air pit Tailings Dam production technology, due to mining methods are different, open-air pit antiseepage and reinforcement means are different,
CHARACTERISTICS OF TAILINGS SAND discharge method is different, and each open-air pit Tailings Dam manufacturing technique method slightly has difference, and main flow is will be dewatered

Step 2: tailing selectivity filling procedure
The tailing ore pulp generated in step 1 is flow automatically by the road into the pulp distribution box for having three-way device,
Mining technique has tailing-filled requirement, adjusts three-way device, and tailing ore pulp is introduced after pumping plant to be delivered to and is adopted
Mine filling process,
Mine does not fill demand, adjusts three-way device, and it is naturally heavy that tailing ore pulp is introduced Tailing thickening pond progress ore pulp
Drop concentration, the overflow water that concentration basin generates is delivered to tailing clarification of water library through pumping plant, under the concentration tailing that concentration basin generates enters
Procedure；
Step 3: Tailing thickening discharges process
It is arranged circumferentially about a circle at concentration basin bottom discharging mouth and rinses hydraulic giant, the concentration tailing in step 2 is adjusted through hydraulic giant
Mass concentration is to after 50%~60%, and gravity flow enters ore discharge pipe network in open-air pit Tailings Dam, and ore discharge pipe network is in open-air pit Tailings Dam
It is interior to be arranged in a ring along the library, gate valve is provided on ore discharge pipe network for ore discharge；
Step 4: Tailings Dam internal drainage process
Watershed is equipped with landing stage of swimming in open-air pit Tailings Dam, and fresh water pump, the clarification of watershed are equipped in ship
Water conservancy enters tailing water clarification library and recycles after being delivered to pumping plant with water pump.
The magnetic induction intensity of roughing operation break-down is 5000 Gausses~6000 Gausses, the magnetic of selected operation break-down in the step 1
Induction is in 4000 Gausses~5000 Gausses.
Ore discharge pipe network uses polyethylene material in open-air pit Tailings Dam in the step 3, and ore discharge pipe network is concentrated along Tailings Dam
After machine arranges that side is drawn, the library along open-air pit Tailings Dam is arranged circumferentially about downwards, and ore discharge pipe network angle of turn is not more than 50 degree.
The fresh water pump installed in landing stage that swims in the step 4 is 3 or more.
Through the above design, the present invention can be brought the following benefits:
The present invention by the improvement to open-air pit Tailings Dam production technology, can effectively solve ore discharge pipe network easily block, bottom storehouse
Space utilization rate is low, the high production problem of fault of water pump rate in library, this method process, clean and effective, small investment high efficiency,
Open-air pit Tailings Dam Years Of Service can be extended and mineral resources comprehensive utilization rate is high, be suitable for copper-sulphide ores, nickel sulfide ore and sulphur
The openpit for changing cupro-nickel associated minerals changes when doing Tailings Dam, carries out the improvement of Tailings Dam production technology.
