Description
Technical field
This utility model belongs to iron ore beneficiation technical field, and in particular to a kind of ore-sorting system of iron content sea sand.
Background technology
In the sea bed in some marine sites, the sea bed in such as some marine sites Indonesian contains abundant iron content sea sand resources,
The Iron grade of some of which sea sand is higher, reaches 30%-50%, if these iron content sea sand can be used, can very great Cheng
The predicament for 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 needs for the ore dressing plant that iron content sea sand resources transport to land to carry out ore dressing all on land, with
Qualified iron ore concentrate is obtained, freight is very high.
2. the iron content sea sand for aspirating up from sea bed, is the relatively low sea water ore pulp of concentration, equivalent to by sea water during sea-freight
Transport together, after when not only to the wind, hull is inclined, sea water is gathered in inclination side, easy shipwreck, and increased invalid transport
Energy consumption, considerably increases cost of transportation.
From the aforegoing it can be seen that cost of transportation is higher to have safety problem with when transporting, the profit of iron content sea sand resources is govern
With being that we are necessary to develop a kind of process is simple effectively this, cost of transportation can be substantially reduced, and do not affect containing for navigation safety
Ferrum sea sand ore-sorting system.
Content of the invention
For the problem that prior art is present, this utility model provides a kind of ore-sorting system of iron content sea sand, it is therefore an objective to drop
Low ore in sand form cost of transportation, and do not affect navigation safety.
The ore-sorting system of iron content sea sand of the present utility model includes sorting system, dewatering system and ore dressing ship, described choosing
, on ore dressing ship, it is that two stages of magnetic separation sorts system wherein to sort system for other system and dewatering system, and a stage magnetic separator is arranged
Above two stage magnetic separators, a stage magnetic separator is connected with the iron content sea sand pump for going deep into sea bed；Described dewatering system is by concentrating magnetic
Machine and filter press composition is selected, the lower section that magnetic separator is arranged on two stage magnetic separators, concentration magnetic separator and filter press is concentrated
Between be provided with concentrate pump, be provided with ribbon conveyer below filter press.
The ore-dressing technique of iron content sea sand of the present utility model, follows the steps below：
(1) the iron content sea sand slurry aspirated from sea bed is fed a stage magnetic separator using iron content sea sand pump, 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 separators, carries out two-stage nitration magnetic
Obtain after choosing mine tailing and two-stage nitration concentrate, a stages of magnetic separation and two stages of magnetic separation mine tailing gravity flow return sea, two-stage nitration concentrate grade >=
50%, the response rate >=70% of ferrum；
(2) two-stage nitration concentrate pulp gravity flow feeds concentration magnetic separator, concentrates magnetic separator by the way of scraper plate discharging, by two-stage nitration
Concentrate pulp is concentrated into weight concentration >=65%, then feeds in filter press through concentrate pump and carry out filter pressing, obtains water after filter pressing
Divide the iron extract mine producation of weight≤8.5%, iron ore concentrate cargo ship is fed through ribbon conveyer, transport land back through iron ore concentrate cargo ship
Utilize.
Compared with prior art, the characteristics of this utility model and beneficial effect is：
(1) of the present utility model sort system and dewatering system is respectively positioned on ore dressing ship, the mine tailing of ore dressing directly flows back to greatly
Sea, builds Tailings Dam like that without land ore dressing plant or carries out tailing dry-heaping, and not only environmental protection does not account for soil, but also
Reduce investment outlay.
(2) of the present utility model sort system and dewatering system is respectively positioned on ore dressing ship, the mine tailing of ore dressing directly flows back to greatly
Sea, transport go back to land is only iron ore concentrate, and freight greatly reduces.
(3) dewatering system of the present utility model is dehydrated by the continuous two-stage for concentrating magnetic separation and pressure filter, final iron ore concentrate
Moisture≤8.5% of product, water yield when so transporting are substantially reduced, and have not only conformed with navigation safety requirement, and greatly
Reduce freight.
(4) system process of the present utility model is simple, and ore dressing ship can be in iron content sea sand place marine site mobile operational process, traffic expense
Substantially reduce, 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 reachable
More than 70%.
