It can be said that Liu Yong has made full preparations for coming to South Africa to develop gold mines this time. Choosing people is a top priority. These 200 people were basically settled after Chen An's rigorous political investigation.

Everything is dominated by one person, and if the person is right, things will be right.

Chen Anxuan's workers are not bad, and they are indeed loyal and capable.

A month and ten days, the first ore began to be produced in the refinery.

In fact, Liu Yong does not understand alchemy. A digression here, the ancient method of alchemy.

The ancient method of alchemy mainly includes manual ore separation, smashing ore blocks, stone grinding ore blocks, ore screening, stirring, pulling flow, fire and other procedures. Among them, the largest number of manual push stone mills, each plate grinding five to six people push, the ancient method of alchemy in the ore grinding after the flow, is to pull the flow, the use of the principle of specific gravity to sweep out the flow of plate gold, the purpose of pulling the flow is to separate the gold from the ore, this is the clear stream, a bit like panning for sand gold, the purpose is to turn the flow plate gold into gross gold, through this procedure, the purity of the wool gold has reached five to six percent of the wool gold after the gold is washed out, with acidic substances to remove impurities, you can smelt, real gold is not afraid of fire refining, about half an hour later, The nugget weighs more than 50 grams, the fineness is about 90%, and it takes seven or eight tons of ore to refine.

The first step of this ancient method of alchemy is to crush the gold ore into the size of soybean grains, and then grind it in the original stone mill until a thick gray mud is grinded.

After the stone mill found the mud, we put him on this flowboard, and then hit the mud with water, because the specific gravity of gold will be relatively large, so he will be hung on this flowboard.

The final process of alchemy is called fire, which is also the most critical step in gold smelting! That is, these wool gold are turned into gold nuggets, and when the fire is turned into fire, the crucible is first burned red with a strong fire, and when the smelted gold water is purified to a certain extent, it is poured into the gold mold, and the gold smelting is completed. The entire process of ancient alchemy is mastered by the experience and feeling of the goldsmith, and the color of the refining is not very pure as soon as possible, only seven or eight percent.

To put it more concisely, it can basically be summarized into five processes:

The first process is grinding: the ore is first put into the water mill, the large pieces of ore are crushed by hydraulic action, and then ground into powder with a stone mill.

The second process is panning. It is to wash the ore powder in water to remove the non-ore part, leaving a powder containing more gold and silver, which is called concentrate powder in the jargon.

The third process is called dough sintering. In other words, the powder containing gold and silver and rice are mixed together to make pellets, which are layered with charcoal to form piles to remove sulfur and sinter into crunchy ore balls.

The fourth process is called lead reduction smelting. The ore mass is mixed and smelted and chemically replaced to form a lead block containing gold and silver.

The fifth process is called the ash blowing method. That is, the lead containing gold and silver is smelted on the ashes of plants and trees, and oxygen is blown in to remove the lead from the lead block. Blowing away the grass ash yields high-purity gold and silver.

This is how Liu Yong's workers worked.

In fact, Liu Yong didn't care what method it was, and he didn't want to study the method of alchemy. It didn't make sense to him. What he cares about is the purity of the gold nuggets. This is his ultimate goal.

His purpose was achieved.

Just a month after the alchemy began, he finally got his first gold nugget.

Haas was hot when he held it in his hand. The gold nugget is about five inches long and about one inch wide, and the word 'Yong' was engraved last year, which means that this is Liu Yong's gold. If you lose it, you can use it to find it. It's kind of a mark.

When he saw this fast gold, it was yellow and eye-catching, and Liu Yong almost trembled with excitement.

Ouyang Lanlan, Su Erniang, Yun'er, and Maria gathered around him, followed by surprise and amazement. I was surprised that my husband had finally made a mirror, and I was surprised that some rough-looking stones could be refined into such a brilliant gold.

Anyway, Liu Yong succeeded.

In the evening, he would feast on the workers and reward them. In the afternoon of the same day, the soldiers were instructed to go and hunt some game. Make a snack for snacks. Ten jars of wine were removed from the ship, so that the workers could drink as much as they wanted.

The workers are also beautiful, and this is also the fruit of their labor. It can be regarded as an explanation to the owner.

They drank wine in big bowls, ate meat in big bowls, and Liu Yong's small building was very lively, just like the New Year. Speaking of the Chinese New Year, it seems that this year can only be spent here, because Liu Yong has to wait until he can pull a boatload of gold to go back. Even if one boat can't do it, that half a boat can do.

Think about it, how much gold is this, that's a ton of gold. It's terrifying.

However, because Liu Yong required that the gold that should be refined should be at least 80% or more, the speed of alchemy was relatively full.

But no matter what, the gold is refined. The next thing to do is to wait, and when there is enough gold, he will load the ship and set sail home.

He is looking forward to this day, Ouyang Lanlan is also looking forward to it, of course, Yun'er, Su Erniang is also looking forward to it. Mary was also full of hope, and she longed to see the most beautiful city in the world that she had longed for. This had already appeared many times in her dreams.

The appearance of Lin'an Mansion in her dream is basically what Ouyang Lanlan, Yun'er, and Su Erniang usually describe to her.

Waiting is also a difficult thing, and when you decide to wait, time seems to become a snail. It climbs so slowly, so slowly. Slow makes people anxious.

Liu Yong is also like this, and he has a feeling of impatience.

But no matter how slow the time is, it will pass.

Two months later, they finally got the nuggets to fill half a cargo ship. That's a lot of money. It is refined by all the workers around the clock. They also knew that the owner was in a hurry to go home. In fact, they are also anxious for the owner to bring their family members.

The gold was packed in the hold of the Eternal, and strangely enough, it was exactly half full, which was easy and pleasant. Liu Yong felt that the amount of gold was at least another ton, which was enough for him to build Lion City Island. It will be his new home.

Before leaving, all the workers handed over their addresses and letters to Liu Yong. They waited for Liu Yongneng to fulfill his promise and bring their other half.

They are so relieved to work for Liu Yong here.

Liu Yong reassured everyone that this thing could definitely be done, unless their other half was unwilling to come. But this is not possible. He also explained that after he left, he should not work so hard to produce, and should pay attention to safety and health.

A meal of care brought tears to the eyes of the workers.

In fact, the gold that Liu Yong took away was their workload for half a year.
