Sam was very productive, and within two days of being out, the guy was back in Kajabi with two cars, the other being a Mercedes GL550 he had just purchased at Mount Issa. In the United States, Sam likes to drive two brands of cars, one is Cadillac and the other is Mercedes-Benz, so Sam bought this car for himself.

Sam also came with an engineering team that came to install the prefabricated house.

At the same time, Sam also brought good news, that is, the two meteorites he sent to the American branch of the International Meteorite Association for identification have been officially recognized as indeed extraterrestrial meteorites, of which the stone meteorite is a lunar meteorite, and the iron meteorite is an out-and-out Martian meteorite.

This news made Tang Feng a little excited, but in a blink of an eye, he began to hide in a place where no one was sad and grimaced.

For the hair? Because when Tang Feng began to condense the symbiotic ore doped with gold, silver, and platinum group metals, the star core actually showed that with the current energy reserves of the star core, it was only able to condense about two-thirds of the ore veins.

In the explanation of the star core, that is, in the current secondary state, the star core is not enough to condense such a huge vein, and the star core in the secondary state, if you want to condense the large molecular weight elements after the forty-fifth position of the periodic table, the maximum condensation is only about 3,000 tons, if you want to condense the elements before the forty-fifth place, this limitation will be gone. And the symbiotic vein that Tang Feng wants to condense this time has a precious metal content of more than 4,000 tons, almost more than 4,300 tons, and all of them are elements after the forty-fifth position of the periodic table, so if the star core wants to completely condense this vein, Tang Feng must continuously replenish energy in the middle!

If he wanted to have no such restriction, Tang Feng would have to upgrade the star core to the three poles to achieve this goal, which made Tang Feng a little depressed. I knew that the star core still had this kind of limitation, and I should have upgraded the star core directly to level 3 when I was in the Olympic Dam, even if it was worth taking some risks.

If the work had been done at that time, there would have been no need to be tired like a dog, condensing the ore veins, and secretly absorbing the natural radioactive elements from a lead-zinc uranium mine in Mount Issa, dozens of kilometers away!

But fortunately, there are enough natural radioactive elements contained in the lead-zinc-uranium mine, which can fully support Tang Feng to complete this condensation operation. Of course, there will inevitably be much less natural uranium in that lead-zinc uranium mine, but that is not in Tang's consideration.

No one could have imagined the real reason why the natural uranium in the lead-zinc uranium mine would suddenly be missing, and who could say clearly about this buried vein? After all, the discovery is the proven, and there is no guarantee of what the true reserves of this vein are, as long as these mines are not dug out, no one can be 100% sure of the true reserves of this mine, so no one will find Tang Feng here.

However, now that there are more people in the ranch, there are seven or eight workers who have built prefabricated houses, so Tang Feng can't stay in the tent without encouragement like the previous two days, and if Tang Feng still does this, he will have to be called by those workers who don't know the truth to summon an ambulance.

The work of condensing and absorbing energy cannot be stopped, so Tang Feng, who was originally quite free, immediately became miserable, pretending to be holding some tools all over the pasture every day, and swaying out of the sight of those workers, and then began to pay attention to the star core.

Fortunately, those workers all know that this young boss is a professional in mineral resource exploration, and people can find out the minerals buried in the ground all day long, which is also an extremely clever skill. At least it's better than building a prefabricated house by yourself!

Entering Australia in March, the temperature is not as high as some time ago, and Australia has entered autumn at this time, which is the best time of the year for scenery and climate. Tang Feng wandered around this pasture of more than ten square kilometers for half a month, and it was not until he condensed the damn symbiosis mine that Tang Feng ended this kind of work that almost drove him crazy.

Having a star core alone is not a panacea! This condensation also allowed Tang Feng to see the fucked side of the star core, but Tang Feng also knew very well that this was all caused by the low level of the star core, so Tang Feng had already been ruthless in his heart - after the work here was on the right track, he had to find a good place to upgrade the star core to the third pole, otherwise it would be really painful!

This condensed vein looks extremely beautiful from the holographic analysis map, this vein was deliberately requested by Tang Feng, and was condensed into a flake vein by the star core, and the average mineable thickness of the deposit is about 3 meters, and the average distance from the ground is only 20 meters. Because it is its own mine, in order to facilitate mining, Tang Feng of course has to condense this ore vein closer to the ground. Flake veins, only about 20 meters above the surface, are very suitable for open-pit mining.

If you want to make a fortune from mining, you have to pay attention to all aspects of cost. There are many steps that need to be taken to turn a silver mine into nothing, and these steps are extremely expensive. Of course, the three main steps are exploration, mining and beneficiation.

Surveying this thing seems simple and doesn't take many people, but in fact the cost of this work is definitely not a small amount. If you want to find a vein from the vast land, the difficulty is not ordinary, and it takes surveyors one or two years or even several years to find it, and the labor cost and survey cost are extremely high.

As for mining, everyone knows that it is the most expensive part of the whole process, and if you don't pay attention, the cost of mining alone can make you unprofitable.

Beneficiation is the process of separating useful minerals from gangue minerals by using gravity separation, flotation method, magnetic separation method, electric separation method, etc., according to the physical and chemical properties of different minerals in the ore, and separating various symbiotic (associated) useful minerals from each other as much as possible, removing or reducing harmful impurities, so as to obtain raw materials required for smelting or other industries. Beneficiation can enrich the useful components in the minerals, reduce the consumption of fuel and transportation in the process of smelting or other processing, and make the low-grade ore can be economically utilized.

To put it bluntly, beneficiation is a process of rough refining.

For Tang Feng, the huge survey cost Tang Feng can be omitted, and similarly, Tang Feng is absolutely unwilling to mine in the open pit, and the mining cost of the latter is several times that of the former. Since the cost of mineral processing cannot be lower than others, as long as the cost control is lower than others in exploration and mining, then there will be huge profits.

That's why Tang Feng made this vein into a vein that can be mined in the open pit.
