Chapter 176: Rare Earth Recovery

Zhang Tao went to the market to buy some pink gangue, the price of gangue is also very cheap in countries with coal mines, its color is very close to the color of rare earths, after buying a car of gangue, Zhang Tao used an ultrasonic resonator to shake them into rare earth-sized pieces, and then packed them all in woven bags, mixed oil and soil are also packed in plastic woven bags, and then cut into long and wide plastic sheets of several meters into bundles, and put them all on the truck.

After arriving, Zhang Tao drove a truck to the dock with the prepared things, and loaded some small barrels of diesel fuel into the three submarines, leaving two submarines, one with pink gangue particles on the package, and the other with diesel fuel and some small submarines and other items.

After returning to the computer room of the factory, he remotely controlled five submarines to sail from the route of the previous departure, and after ten days, the three submarines loaded with small barrels of diesel were all under the submarine and hid in the caves that had been carved out, and the two submarines were remotely controlled to bypass the Bering Strait and sail towards the direction of the North Pacific Ocean near the Russian Sea.

A few days later, he remotely controlled two submarines to a place one thousand meters away from the hill of Landing Ao Bay, released a small submarine disguised as leatherback turtles, let the two submarines dive to the bottom of the sea, came to a trench and turned on the vibration frequency of the ultrasonic stone, shook out the cave with two shells to accommodate three or two submarines, and then remotely controlled the two submarines into the cave and then talked about the collapse of the hole, and there was a large space for a submarine in the cave, Controlling the robot in the submarine, attaching ultrasonic devices and shovels to the manipulators of several small submarines, and then releasing them into the cave.

Then remotely controlled several small submarines in the direction of the hill, using ultrasonic devices and shovels to dig a hole that could pass through a submarine, digging until the second half of the night, Iceland's time also entered the night, controlled several small submarines back to the submarine, filled up the tank, turned on the vigilance detectors of the two submarines, Zhang Tao washed up and fell asleep in the computer room.

After ten days, the passage was opened, in fact, the time to dig the hole was enough for a few days, and the extra time was used to transport the soil in the hole to the seabed outside the hole, and the small submarine would turn on the ultrasonic detector every time it dug to check whether there were metal and other utensils around the top of the channel.

It was not until the bottom of the hill that it was detected that there were several metal objects above the hill, and according to the shape and position of the reflection, Zhang Tao judged that it was a battery to charge the camera, and the top of the hill was dozens of meters away from the sea, so it was not a problem to transmit signals over a short distance.

At the end of the channel, the rare earth wrapped in plastic cloth is exposed, and the size of the plastic cloth is one meter long and half a meter wide after measuring, after taking down one of the rare earth blocks above, I saw that the rare earth blocks exposed above were placed vertically, and after the rare earth blocks were taken out, the sea water poured in to fill the position of the rare earth blocks, and after taking down a rare earth block, the rare earth blocks above did not fall under the pressure of the surrounding rare earth blocks.

After taking down the two pieces of rare earth wrapped in plastic sheeting, the robot in the remote control submarine cut the plastic sheet to the size of one meter and half a meter in length and width respectively, and then opened a woven bag containing gangue fragments, stirred the gangue with seawater in the ballast for a while, and then wrapped it with the cut plastic sheeting, and then took out some of the oil and soil packaged in the woven bag, smeared it on the bottom plastic sheet, and then sprayed some on the oil and soil with seawater, so that the water evaporated by the oil and soil can be replenished and the viscosity increased.

The gangue particles are also more sticky after being mixed with water, and the oil and soil outside the plastic sheet have some plastic properties, and after a while, a shape is the same as the rare earth block, and after making two gangue blocks, he controls a small submarine to bring the two rare earth blocks back to a submarine with a free place, and then comes to another submarine to transport the two gangue blocks to the hill and put them in the original rare earth block.

After replacing all the rare earths in the bottom layer of the hill except for the outermost rare earths, the space in the submarine is full, and the outermost one is not moved to prevent the RB people from checking it out, after all, the fake can't replace the real one, and the outermost one can be real, no one would have thought that someone would dig a hole in the bottom of the sea silently to transport away the rare earth blocks.

Some of the surrounding sand is backfilled with a small submarine to prevent anyone from discovering the cave under the seabed, although this is less likely, and if you have an ultrasonic device in hand, it will only take a little more time to get back.

After dark, he remotely controlled the two submarines out of the cave where they had been staying for more than half a month, and the ultrasonic frequency of the stone turned on the cave to completely collapse and completely seal the hole. Then, they floated up and retracted the small submarine disguised as leatherback sea turtles and headed for the Tsugaru Strait.

More than half a month later, the five submarines all returned to the island base, put the rare earths harvested this time in the storage room in the base, and then remotely controlled the robot to inspect several submarines, and after replacing some parts, they plated a layer of chromium on their shells.

With rare earths, some electronic parts and motors and other equipment are easy to manufacture, rare earths are a catalytic role, Zhang Tao saw in the data that a small amount of rare earth mixed with water to spray crops will increase the yield, similar to the lack of vitamins in the human body, it belongs to the vitamins in the metal. Now make the missiles and satellites first, and when Zhang Tao is at leisure, he plans to bring back a batch of rare earths to water flowers and spray the crops in the farm to increase the yield.

After the manufacturing program of the missile shell and the circuit board of the satellite are entered into the computer and transmitted to the island base, the robot and machine tool will automatically process them, and all the small parts will be processed in several copies, and the extra ones will be kept for backup.

Now it's November, the water in the sea is also a little cold, Lin Xin and the girls rarely come over, basically Zhang Tao drove the yacht back to the farm, and it was very convenient to drive the yacht for half a day.

In his spare time, Zhang Tao also invited his father-in-law Sigting to come to his seaside villa to shoot targets, the shooting range of the training ground is very large, Zhang Tao will shoot a few shots every day to play, the big pearls harvested in the Atlantic Ocean are drilled with a drilling machine and then worn into dozens of pearl necklaces, and the remaining small pearls are also a head of about ten millimeters, and a lot of them are drilled into pearl necklaces and given to themselves and their relatives.

The remaining relatively large Zhang Tao plans to keep them and sell them separately, and remotely controls the robot on the island base to do a full body inspection of Robot One, and after finding no problem, he switches the remote control and operates Robot One to enter a submarine with documents and money, bank cards and micron-level robots, and remotely controls the submarine out of the base and drives towards the British waters.
