Chapter 462 (1/2)

The 7000 meter long track, like a seaweed in the sea, sways slowly with the ocean current.

The 500 meter long graphene track is connected by titanium alloy rings at both ends. The 14 segmented tracks make up the ladder from the deep sea to the shallow sea 7000 meters below.

The cost of the whole track is 5 million yuan, which is almost equal to the total amount of NAC's food trade in a month.

In the whole set of equipment, the highest cost is the 15 titanium alloy rings. It can not only fix the graphene orbit, but also control the water depth as freely as a submarine. And according to the current direction, the titanium alloy ring can also move in the opposite direction through the blade engine with four angles to prevent the huge tidal force tearing the entire graphene track.

When the water drop's robotic arm placed the six meter long and two meter diameter elliptical ”elevator” on the bottom track, the entire subsea mining device was fully deployed.

Two suction cups under the water crush the marine sedimentary rocks, and then transport the broken rocks to the ”cylinder” through the graphene hose. After primary beneficiation, the cylinder is subject to secondary fragmentation. The sedimentary rocks with poor hardness are crushed into pieces and blown into the sea directly through the screen. The manganese nodules with higher hardness can be screened and sent to the ”elevator” at the top.

When the elevator is filled with minerals, the segmented graphene guide is energized. The whole ellipsoid, like the shell of an electromagnetic gun, is accelerated by the graphene guideway to the shallow sea area.

When the minerals are sent to the shallow water with a depth of about 100 meters, the current equipment can also be used for fishing.

The staff on standby on the offshore platform only need to follow the signals from the sea. Once the minerals are confirmed to have been sent up, a fishing boat will be sent to pick up the minerals to a depth of 100 meters by divers and trawlers.

After a certain amount of minerals are accumulated on the offshore platform, they are then transported to the manganese nodule refinery in ANGA island for refining. At that time, the new country's iron, manganese and molybdenum will no longer need to rely on imports, and its own production can also meet the industrial needs of ANGA island.

After all this, Jiang Chen deployed two ocean current generating units, which are made of 3D printing, on the seabed to supply power to the entire mining facility.

Including shuidi No.1, the cost of the whole set of facilities has exceeded 7 million sub crystal.

Although it is no doubt that some of them are expensive, Jiang Chen believes that the investment is definitely worth it.

Nothing else. Even at the market price of the sixth block, the price of a kilogram of molybdenum ore is about 10 sub crystals. As long as 700 tons of molybdenum ore is mined, the cost will be almost back.

And the reserves of the seabed manganese nodule deposit are more than one million tons?

The whole set of mining equipment has been mined in the current sea area for ten years without any problems.

After returning to coconut island. Jiang Chen called Yang Yuan and told him that he could start mining.

”The problem of seabed mining has been solved?” When Jiang Chen said that he could send workers to work on the offshore platform, Yang Yuan immediately asked in surprise.

”Yes, I'll send you the specific mining process by email. One ore carrier, one fishing boat, two divers and one observer. That's all you need. ” Jiang Chen laughs.

Yang Yuan frowned suspiciously.

”But how do you get the mine out of the deep sea? Don't tell me to let the divers go to 7500 meters to get the awl chisel. ”

”When I'm an idiot?” Jiang Chen said with a smile, ”OK, you don't have to worry about it. I have solved it. I'll send you an email soon, and you will know what happened to the whole mining equipment. The cutting-edge technology of futureman group, don't be scared at that time. ”

Yang Yuan glanced at his mobile phone.

I'm kidding. Anyway, I'm a graduate student from the University of Western Australia, and I signed a contract with Rio Tinto in my first year of graduate school. What mining equipment have you never seen?

It was the first time that he had heard of something that could pull ore from 7000 meters under the sea.

”All right. You can send me the mail

”Well, wait.”
