This is the sixth day of entering Shanghai, in the wharf by the river, a large number of canopy boats parked here, this is Wuhan's Yang Shixun's, do everything possible to get the black stone, a total of 4800 tons, with 48 large large river boats, it took almost a week, this is here, at this time, Harpy has already passed the Guò Public Works Bureau, looking for enough dock workers, and a team of Indian soldiers to take care of it.

"Which one is Young Master Yang!" A man who looked like a steward walked out and asked Harpy and the others.

"I am!"

"I am Yang Guanhu from Jiangxi, and I was ordered to escort 48 ships of Heishi to come, a total of 4,800 tons of metric system, please sign for it Young Master Yang!"

Yang Yuanzhao in the Yang Family Chamber of Commerce, received a telegram from Yang Shixun, the collection of black stone is relatively smooth, but the capacity can not be satisfied, if the use of steamboats, the cargo capacity is huge, but the price is also relatively expensive, so, a total of three batches, will be transported in the next week, the number of each batch has also been determined, the first time is the most, is 4800 tons, the second is only 4000 tons, the third will reach 3200 tons, a total of 12000 tons.

Such a huge number, Yang Yuanzhao is very satisfied, tungsten is a military material, but in exchange for huge benefits, there must be enough quantity, 12,000 tons, regardless of the quality, as long as the content is more than 0.5%, you can produce 60 tons of pure tungsten, this metal, to Germany, is a huge weight.

Harpy knows that Blackstone, which is also Germany's key procurement, most of them are in the field of military industry, he is a small businessman in this field, even if he has a little background in his hometown, he can't intervene, according to the bill of goods and prices he just saw, such a price, even if it is a change of hand and a foreign company, a ton can earn at least 3-5 silver dollars, he suddenly understands a little, why Yang Yuanzhao would rent such a large warehouse, with Yang Yuanzhao's influence in China, he can meet foreign trade casually, for foreign banks, Mainland relations, which are the most difficult to get through, have suddenly become clearer.

If Yang Yuanzhao knew what Harpy thought, he would definitely laugh off his big teeth, the change of hands of blackstone is only a few dollars a ton, but if tungsten is extracted from blackstone, the price is absolutely different, the smelting of non-ferrous metals in this era is definitely just starting, not only the cost is huge, but also the pollution is huge, so the price of the refined metal and ore is almost worlds apart.

Harpy had already prepared manpower, 4,800 tons of black stones, all loaded on a special truck, nearly 100 porters, it only took about 2 hours to get these black stones, all of them to the warehouse.

Blackstone is heavy, profitable but not high-priced, except for some German businessmen, imported blackstone business, other people have little contact, Harpy's identity as a German, a certain amount of dù, became a necessary cover-up, no one noticed, there is a batch of 12,000 tons of blackstone, transported to Shanghai, quietly into the warehouse.

The specific gravity of blackstone is large. 48 million tons of black stone, it is only a few hundred cubic meters, except for the innermost room, the rest of the warehouse is empty, just pile it up, anyway, it is ore, and it is not afraid of wind and rain, under the condition that no one pays attention, Yang Yuanzhao quickly absorbed part of the black stone and tested it.

Blackstone is actually tungsten ore, tungsten ore is divided into scheelite and wolframite, in this era, scheelite has not been found for the time being, more is wolframite, depending on the mining and exploration of this era, wolframite is often mixed with other ores, and even local mine owners, for the sake of adulteration of interests, it is obvious that the Yang family still has some roots in Jiangxi, they provide this batch of ore, the quality is relatively average, Yang Yuanzhao from several directions, have made tests, tungsten content is 0.87% -1%, in later generations, is almost equivalent to high-grade concentrate.

At this point, in Yang Yuanzhao's heart, a big stone, completely put down, close to 1% of the content, the Yang family from Jiangxi transported from the black stone mine, 12,000 tons, at least can be refined close to 120 tons of refined tungsten powder, such a pure tungsten powder, a certain amount of dù above, in this world, is an absolute strategic resource, the price is extremely high.

A ton of black stone, even if it is transported to Germany, will not exceed 100 marks per ton, among them, businessmen can earn 15-20 marks of profit, in addition to the intermediate transportation costs, it is not satisfactory, Lihe foreign companies and other German-funded foreign companies have been doing this, more because of strategic reasons, since the discovery of the role of tungsten in the alloy, Germany has been trying to find a way to buy raw ore, for China, where Germany's power is relatively weak, still sent a large number of personnel.

Blackstone ore transportation is inconvenient, if tungsten powder, not only the transportation volume will be reduced a lot, the cost of transportation will be greatly reduced, even if it is the price, it will soar, generally speaking, the price of a ton of tungsten concentrate powder, between 400,000-500,000 marks is 10,000 times, the cost of extraction, not to mention, technology is also a major problem of constraints, in the whole world, in addition to Germany, only the United Kingdom and the United States large-scale test, there is a small batch of extraction.

The high cost of refining from blackstone ore to tungsten concentrate powder, in front of Yang Yuanzhao, is nothing, the current decomposition capacity of the all-in-one machine, 8 cubic meters in 10 minutes, more than 1000 cubic meters a day, of course, to avoid some eyes, it takes a few days to complete, barely countable, the time they spend in Shanghai, urea, seeds, phone bills, and a large number of plastic films and some machines, have been on board in advance, they travel lightly, as long as in April, rush back to Shanxi has been able.

In the warehouse, the porter was sweating and raining, and the pounded black stones were stacked in the warehouse, and Harpy and the hired accountant began to calculate, and after completion, they would give a reply to Yang Guanhu, who would take it back to Wuhan and exchange the 100,000 silver dollars that Huàn had saved in the Weijia ticket number, which was a more rigorous process.

In the end, when all the goods were written down, it was already more than 2 hours later, Yang Yuanzhao quietly collected 100 cubic meters of black stone, stopped the ongoing slag refining, and began the refining of tungsten ore powder, which was a key to his future, and he had to race against time.

After getting the receipt, Yang Guanhu did not stay here too long, he told Yang Yuanzhao that the remaining two batches would arrive in Shanghai in 3 days and 5 days, and he would wait at an inn and inform them when the goods arrived.

A large transaction at the level of 100,000 yuan, even if it changes hands now, the big business of 70,000 or 80,000 yuan that can be earned has given Harpy a new understanding of Yang Yuanzhao's strength, a large number of blackstone mines, a large number of arms, and he is suddenly full of confidence in the next life.

Sitting in the carriage, on the surface, it seems that he is closing his eyes and recuperating, but his consciousness has entered the all-in-one machine, the previous decomposition has been completed, looking at the powder in his hand, showing a silver-gray metallic luster, Yang Yuanzhao's face showed a smile, tungsten essence powder, the content is more than 99%, enough to cope with any alloy addition, it can be said that he can find at present, large quantities, the best decomposition metal, and it is also a strategic metal.
