This is where the placer machine comes in.

Simply using manual washing, thirty or forty people could not wash seven or eight loads of mineral soil in a day, but with a placer machine and a water pump, it only took five or six minutes; before there were excavators, most people only needed

Just be responsible for digging and transporting the soil.

"Gold has come out! Gold has come out!" Potu shouted excitedly, holding the water gun crookedly and getting wet all over Cao Mo.

"What's so weird about this? You're such a bastard, you've wet me all over." Cao Mo scolded with a smile, and told Botu to quickly grab the water gun and spray him all over. Don't wash away the gold powder that was finally absorbed on the gold-absorbing blanket.

This is just the beginning. Even half a gram of placer gold may not be enough.

Since Botu was so excited, Cao Mo felt that since Botu had been by his side during this period, there were probably not many people saying dejected words in front of him.

…………

…………

Cao Mo suppressed his inner excitement and pretended not to care.

Although the whole process was very simple, Cao Mo still repeatedly looked at the connection of each link. If there was any incorrect operation, he would correct it and teach the employees some commonly used Chinese words.

The process of panning for placer gold is also simple. It is to put the placer gold in a sandalwood gold pan, put it in clean water and gently shake the gold pan. Let the sand fall from the gold pan into the bucket. If it stays in the gold pan, it will be relatively pure.

It can even be sold directly as gold.

When dusk was approaching and everyone had finished work, Cao Mo walked back patiently and watched as Botu weighed and recorded the small amount of placer gold he had earned in a day, then handed it to Kabuga and locked it in an old safe.

There were a lot of imperfect connections on the first day.

After reminding me for several days, I still cannot stop the phenomenon of arriving late and leaving early and coming in and out at will.

Kabuga wanted to catch a typical example and grabbed the two of them to punish them, which almost led to a fight. However, Owema knew what was wrong and pulled the two troublemakers away with curses, but he had no way to solve the problem of arriving late and leaving early.

question.

The gold mining team are all tribal villagers. They are still accustomed to treating the gold mining team as farmland and dense forests near their residences, and have not developed strict labor discipline.

Except for Kabuga, Overema, Potu, Pali, etc., fortunately Cao Mo did not officially disclose the salary policy beforehand. He first held a small meeting, then summoned all the workers, and announced that in the future, they would

The salary of one thousand five hundred naira (five dollars) per week is basically that if you can guarantee not to be late, leave early, not slack off in the middle of the work, and obey the management, you will get an additional bonus of one thousand five hundred naira per week.

In other words, every worker who works conscientiously for a month can receive a high salary of forty US dollars or three hundred and twenty yuan.

Just this stupid thing took up a lot of time.

Both Botu and Pali could not understand the problem of water pump elevation, so they tried to move the placer closer to the slope in order to shorten the distance of moving soil back and forth, which wasted a lot of time.

The road between the sloping land and the placer machine was built carelessly because Overmar did not pay enough attention to it before, and the people who led it were very careless. Some of them fell into the ravine with their vehicle. Fortunately, nothing happened to them.

At the final weighing, fifteen grams of placer gold was collected in one day, which was far from equaling the cost of one day, let alone the initial investment in equipment, but the members of the gold mining team were very encouraged.

After all, this is fully twice the amount of gold they mined before.

After three days, all aspects of the process gradually became smoother.

Compared with tradition, there is nothing complicated about the new placer gold mining. Even if the members of the gold mining team have not received much education, they are still young and middle-aged people in the tribe with flexible minds and hard-working hands. They were recruited by the old chief Felic.

Angie and Overema singled out.

From now on, the amount of gold mined every day will be stable at more than 30 grams.

Although this has not yet reached Cao Mo's expected goal, it can barely cover the cost.

Half a month later, Cao Mo's small amount of cash was almost exhausted due to his constant purchase of diesel and other materials. At this time, he also accumulated 500 grams of placer gold.

Cao Mo took out the placer gold from the safe, used a small amount of mercury to absorb it, and put it into a tong pot. Then he took out a high-pressure oxygen gun and smelted it into gold water.

When you see gold water foaming in the middle, add some borax to remove impurities. Wait until the alluvial gold completely turns into red gold water. Pour it into a long mold groove as quickly as possible. Apply a layer of oil to the mold groove in advance, and pour the gold water into it.

, it will take shape immediately and turn red. Let it cool naturally for a while, then put it in cold water to continue cooling.

These processes and materials were introduced in detail, but this was the first time Cao Mo had done it himself, and his hand holding the hyperbaric oxygen gun couldn't help but tremble a little.

Five hundred grams of alluvial gold, a large number of impurities in the middle are removed, and finally smelted into a fairly pure gold bar, about less than 460 grams.

This is the output of the gold mining team in more than half a month.

At the end of June 2004, the international gold price was only US$3,890 per ounce, and a 460-gram gold bar was worth only about US$5,000.

To be honest, even if more than half a month's US$5,000 is a pure profit, it is not a sudden windfall in Kanem; and such a large output, after deducting the costs of material consumption, equipment depreciation, labor wages and other costs, is almost nothing.

What profit is there?
