Description
Technical field
The invention belongs to iron ore beneficiation technical field, be specifically related to ore-sorting system and the ore-dressing technique of a kind of iron content sea sand.
Background technology
Abundant iron content sea sand resources is contained at the sea bed in some marine site, the such as sea bed in more Indonesian marine sites,
The Iron grade of some of which sea sand is higher, reaches 30%-50%, if these iron content sea sand can be used, and can very great Cheng
The predicament alleviating China's land iron ore deposit scarcity of degree.The utilization of iron content sea sand iron ore deposit, main bugbear is by two aspects:
1. the ore dressing plant of iron mine is all on land, needs the ore dressing plant that iron content sea sand resources is transported to land to carry out ore dressing, with
Obtaining qualified iron ore concentrate, freight is the highest.
2. the iron content sea sand aspirated up from sea bed, is the relatively low sea water ore pulp of concentration, is equivalent to sea water during sea-freight
Transporting together, after when not only meeting wind, hull tilts, sea water is gathered in inclination side, easy shipwreck, and adds invalid transport
Energy consumption, considerably increases cost of transportation.
From the aforegoing it can be seen that there is safety problem when cost of transportation is higher and transports, govern the profit of iron content sea sand resources
With, for this, we are necessary to develop a kind of technique simply effectively, can be substantially reduced cost of transportation, and not affect containing of navigation safety
Ferrum sea sand ore-sorting system.
Summary of the invention
The problem existed for prior art, the present invention provides ore-sorting system and ore-dressing technique, the mesh of a kind of iron content sea sand
Be to reduce ore in sand form cost of transportation, and do not affect navigation safety.
The ore-sorting system of the iron content sea sand of the present invention includes the system that sorts, dewatering system and ore dressing ship, and described sorting is
System and dewatering system are arranged on ore dressing ship, and the system that wherein sorts is that two stages of magnetic separation sorts system, and a stage magnetic separator is arranged at two
Above stage magnetic separator, a stage magnetic separator is connected with the iron content sea sand pump going deep into sea bed；Described dewatering system is by concentrating magnetic separator
Form with filter press, concentrate magnetic separator and be arranged on the lower section of two stage magnetic separator, concentrate between magnetic separator and filter press
It is provided with concentrate pump, below filter press, is provided with ribbon conveyer.
The ore-dressing technique of the iron content sea sand of the present invention, follows the steps below:
(1) utilize iron content sea sand pump that the iron content sea sand slurry of suction on sea bed is fed a stage magnetic separator, through a stages of magnetic separation
Machine obtains mine tailing and one section of concentrate after carrying out a stages of magnetic separation, one section of concentrate pulp gravity flow feeds two stage magnetic separator, carries out two-stage nitration magnetic
Mine tailing and two-stage nitration concentrate is obtained after choosing, the mine tailing gravity flow return sea of a stages of magnetic separation and two stages of magnetic separation, two-stage nitration concentrate grade >=
50%, the response rate >=70% of ferrum；
(2) gravity flow of two-stage nitration concentrate pulp feeds concentration magnetic separator, concentrates magnetic separator and uses the mode of scraper plate discharging, by two-stage nitration
Concentrate pulp is concentrated into weight concentration >=65%, then feeds through concentrate pump and carry out filter pressing in filter press, obtains water after filter pressing
Divide the iron extract mine producation of weight≤8.5%, feed iron ore concentrate cargo ship through ribbon conveyer, transport land back through iron ore concentrate cargo ship
Utilize.
Compared with prior art, the feature of the present invention and providing the benefit that:
(1) system that sorts and the dewatering system of the present invention is respectively positioned on ore dressing ship, and the mine tailing of ore dressing directly flows back to sea, and
Need not ore dressing plant, land build Tailings Dam like that or carry out tailing dry-heaping, not only environmental protection, do not account for soil, but also save throwing
Money.
(2) present invention the system that sorts and dewatering system be respectively positioned on ore dressing ship, the mine tailing of ore dressing directly flows back to sea,
That transports go back to land is only iron ore concentrate, and freight is greatly reduced.
(3) dewatering system of the present invention is dehydrated by the continuous two-stage concentrating magnetic separation and pressure filter, final iron extract mine producation
Moisture≤8.5%, so transport time the water yield be substantially reduced, not only conformed with navigation safety requirement, and greatly reduced
Freight.
(4) system process of the present invention is simple, and ore dressing ship can be at marine site, iron content sea sand place mobile operational process, and traffic expense is significantly
Reducing, operating cost is low, and the grade of ferrum can bring up to more than 50%, for the response rate of magnetic iron ore sea sand ferrum up to 70% with
On.
