Of course, Tang Feng did not do too much to cut off children and grandchildren, the effect was too obvious, and it was very inconsistent with scientific principles, so Tang Feng selected the purified ore layer, which is located in the area 30 meters below the deepest excavation face of each of the three major mines.

And the diamonds purified by Tang Feng are all rough diamonds that have reached gem-quality diamonds, as for those diamonds that cannot reach gem-quality, Tang Feng is too lazy to purify them, so he simply leaves them all to Dai. Bills dig slowly. Anyway, only a very small part of the diamonds you dig out can reach the standard of diamonds, and Lao Tzu just makes you work hard and laborious, but in the end you find that it is working in vain.

The star core is a very magical existence, once Tang Feng gives the order, the star core starts to operate automatically. From the purification of the rough diamond to the storage in the receiving space, everything did not need Tang Feng's own hands, and two hours later, in a certain corner of the star core space, a pile of rough diamonds with about sixty tons appeared

Consciousness drilled out of the space and looked at the watch, and found that the time had just passed more than two hours, and Sophia beside him was still asleep, so Tang Feng simply didn't do anything, and his consciousness entered the star core again, adjusted the length of the transformation function, and began to attack the Vinitia diamond mine in South Africa.

The process was similar to dealing with the three major diamond mines just now, except that the diamond reserves of the Vinitia diamond mine were obviously smaller than those three mines, and after two hours, the pile of diamonds had only increased by less than fifteen tons of rough diamonds

After finishing the Venitia diamond mine in South Africa, Tang Feng set his sights on the diamond coast of Namibia.

Compared with the three major diamond mines in Botswana and the Venitia diamond mine in South Africa, Tang Feng is a little reluctant to attack the diamond coast of Namibia.

Namibia is also a country that suffers, and although it is one of the few countries in Africa that did not experience the devastation of World War I and World War II, it is not very rich until now. Although the GDP per capita of this country may seem like quite a few. But in reality, the country's economic lifeblood is controlled by a handful of tycoons, and the vast majority of ordinary people still live below the poverty line.

And in this country, industry and mining are the backbone of the country's economy, especially diamond mining and uranium mining, which account for nearly half of the country's total economy. Many Namibian people live by diamond and uranium mines.

Namibia's uranium mines can be left untouched, but if the diamond mines are taken away. Tang Feng himself was a little unbearable.

However, fortunately, the diamond coast of Namibia is extremely vast, and the entire diamond mining area is also huge, even if Tang Feng moves it all, he will be a little unable to catch it at such a distance.

Namibia's diamond coast is home to the world's largest diamond secondary vein ever discovered. Centered around the small coastal city of Lüderitz in Namibia, this vein belt extends nearly 350 kilometers to the north and south and nearly 120 kilometers wide in the vast Namib Desert. In other words, the world's largest secondary natural diamond mining area is a huge mining area with a length of more than 700 kilometers from north to south and a width of about 120 kilometers from east to west. The total area is more than 80,000 square kilometers!

This huge natural diamond secondary mining area was formed by the alluvium of some rivers millions of years ago or even tens of millions of years ago. The Orange River, which flows through the Kimberley near the Kimberley, the capital of the Northern Cape Province of South Africa, has been diverted several times over millions of years, leaving a large amount of rough diamond washed over the Kimberley Rock Belt in South Africa in this vast desert, and after millions of years of sedimentation, it has finally formed the world's largest natural diamond secondary vein area.

Before 1908, it was estimated that no one in the world could have imagined that under the sand dunes of the arid Namib Desert. There are crazy diamonds buried.

Namibia was a German colony during the colonial period before it became independent. 1908 year. The German colonists built the railroad to the small town of Lüderitz, and one day, a black brother who built the railroad picked up a few strange stones, and it happened that the black brother had stayed in Kimberley, the "diamond city" of South Africa, he recognized these stones as diamonds, so he handed them to his German boss Stanz. Stanz quietly evaluates the diamond. After determining that it was a top-quality diamond, he quietly bought ownership of the desert where the diamond was found.

As soon as the news broke, the once desolate desert became a treasure, and people from all over the world came here to dig and drill. The German colonial authorities declared the area from Lüderitz to the Orange River a "no-go zone" and allowed only one German company to exploit it. Until 1914, when the First World War began. Over the course of six years, more than 4.6 million carats of diamonds were produced in this "exclusion zone", which was worth £7 million at prices at the time.

But what the Germans didn't expect was that their authoritarian decision would instead trigger another "digging fever". Large numbers of drill diggers swarmed into the Namib Desert north of Lüderitz. In less than two years, more than 500 people have registered to dig in this desert.

This vast desert area is the origin of Namibia's advanced diamond coast.

After World War I, the defeated Germans lost control of the Diamond Coast. Sir Oppenheimer bought the mining rights in Namibia with deep pockets and became the sole owner of the Diamond Coast.

Later, when Namibia declared its independence, this huge mining area buried with crazy diamonds became the responsibility of the Namibian government and Dai. The area that Bills is co-in over. Even now, the vast area between the Quesbu River, which flows into the Walvis Bay Harbour in the north, and the Orange River, the boundary river between Namibia and South Africa in the south, is strictly restricted from entering and exiting. A diamond mining area demarcated by Beers.

However, the most important diamond-producing area of the proven area is the Orange River estuary, which is the main production area of the Diamond Coast within a hundred kilometres on the north and south sides of the estuary.

In other areas of the Diamond Coast, Tang Feng does not plan to do anything, Tang Feng plans to take away the diamond mines in the area near the mouth of the Orange River. In fact, the person responsible for mining in this area is still Dai Dai. Bills is dominant. Since Tang Feng didn't want to involve more ordinary people in Namibia, it was most appropriate to choose this location. (To be continued.) )
