Andrew took a basin and filled it with sand from the river, and the test wash was a sample to see if there was gold ore in the area, and how rich the gold ore sand was. Pen, fun, pavilion www. biquge。 info

The specific gravity of gold is 15 times that of water, and the specific gravity is larger than that of sand and gravel, with the rinsing of the water flow washes away the sediment, and finally, only gold ore remains, the most primitive gold panning is the use of this principle, for example, the gold rush in the United States gold diggers were first panned for gold in this way, until now, most of the gold panning equipment in Alaska is more advanced, and the gold panning efficiency is higher, but the principle is that the water flow washes away the sediment, and the gold ore with a greater proportion is precipitated in the drainage tank.

Andrew has 2 or 30 years of experience in gold mining operations in Alaska, and is a very good miner, he can win many jobs such as technician, foreman, miner, etc., although Chen Yan is the mine owner, in the entire gold mining team, the core is Andrew.

Half an hour, the results of the test wash came out.

"How?" Miner Wren asked.

"I think I'm going to make a fortune this mining season." Andrew said, and after speaking, he handed the basin in his hand to Chen Yan.

Chen Yan took the basin and looked at it, there were at least dozens of pieces of gold sand at the bottom of the basin.

"Look at this piece of gold, the nails are big, and it is rare for Alasra to have such a large piece of gold."

"At least $70 a yard, and it's rare to find such an abundance of gold in Alaska, but it's only possible in California."

"What are you waiting for, guys, get moving, I promise that each of you will be rewarded handsomely when the mining season is over."

.....

Chen Yan hired them, asking for a salary of several thousand dollars a week, as well as a share of the gold, Andrew 3%, Wren and Locke 1%, if the whole mining season can be mined 2,000 ounces of gold, 1%, is 20 ounces, worth 20,000 US dollars, a lot, so, every miner hopes to be able to mine more gold in the whole mining season, only gold can make them full of energy.

The $70 test wash got everyone excited.

"Let's start acting, we are going to set up the washing equipment today, and tomorrow, I want to see the washing equipment working properly." Andrew said.

The heavy truck transported the panning equipment, and everyone worked together to erect the panning equipment, install it, and debug it so that it could work normally tomorrow.

By the time this was done, it was already night.

......

The next day.

Everyone got up early.

The washing equipment is erected on the bank of the river, and an excavator is needed to dig out the sand and gravel containing gold ore sand in the dry riverbed and pour it into a truck, which transports the sand and gravel to the shore and dumps it in the open space, and finally, an excavator pours the sand and gravel into the funnel, and the baffle screens out the coarse stones, and then the sand and gravel soil is washed on the drainage tank, and the gold with a large proportion is precipitated in the groove of the drainage tank.

Wren manipulated the excavator to dig the sand and gravel containing gold ore in the riverbed, Locke drove the truck to transport the sand and gravel, and finally Andrew manipulated the excavator to pour the sand into the funnel.

Chen Yan started the washing equipment in front of the equipment, started the water pump, the conveyor belt of the washing equipment rotated, the water pump pumped the water from the creek and sprayed it on the drainage tank, and used the flow rate of the water flow to wash away the sediment, and the gold with a large proportion of gravity was precipitated in the groove of the drainage tank.

......

The elution equipment is operating normally.

After the equipment was washed for 500 yards, Chen Yan turned off the equipment and the water pump.

If the water flow is too large, the gold has not settled in the groove of the drainage tank, or the drainage tank cannot effectively precipitate the gold, then the gold is likely to be washed out of the drainage tank, then, everyone's work before is in vain, and the gold is lost.

Chen Yan looked at the sediment flowing out of the drainage tank, fortunately, no gold was found in the sediment, if gold was found, then it was a big problem, it was very likely that everyone's hard work for several hours was in vain, and the gold was lost.

Chen Yan saw that all the gold had settled in the grooves of the drainage groove, and inside the fine sand, the golden light was shining.

Chen Yan wanted to see how much gold could be mined with one yard.

Chen Yan rolled up the mat, poured the fine sand on the mat and the gold in the fine sand into the bucket, and used a finer and smaller washing equipment to wash the gold sand out of the fine sand.

......

There was a lot of gold washed out, and a bottle was filled.

"Guess how many ounces there are." Chen Yan said.

"40 ounces."

"More than that, 50 ounces, I guess."

"Weigh it and you'll know."

......

Chen Yan poured the gold sand on the electronic scale.

"20 ounces."

"30 ounces."

"It's 40 ounces."

"45 ounces."

"47.7 ounces."

......

Chen Yan took a computer calculation that the gold price was $1,200 per ounce, 47.7*1,200 = $57,240, 57,240/500 yards, and one yard was close to $115, far exceeding the estimated $70 per yard when it was tested.

"$115 a yard, guys, Numa Creek is definitely a big gold stream."

Including, Andrew, Wren, Locke, everyone had an excited look on their faces.

Andrew's bear-like figure was so excited that he danced excitedly, dancing and singing, "I'm a miner, I'm a miner, I'm going to mine gold, I'm going to mine more gold,......。 ”

Wren was rigid and had a smile on his serious face.

Locke was eager to start the excavator and pour truckloads of sand into the funnel.

This mining season is their fortune season, except for California during the gold rush, there is only a yard of $115 big gold stream, in Alaska, a yard of $10, $15 gold panning, can gold diggers harvest a sum of money throughout the gold rush season, a yard of $115, it is simply a river of gold.

Today, after only one morning, they harvested more than $57,000 worth of gold, and Wren and Locke could get 1% of the gold, $570, and at least a hundred thousand dollars worth of gold could be distributed for them throughout the mining season.

Everyone is energized.

-------

A yard of $115 worth of gold in Numa Creek quickly spread throughout Alaska, and the whole of Alaska spread that Numa Creek is a river with open gold, and the golden sand at the bottom of the river sparkles in the refraction of the sun.

A piece of dog-headed gold the size of a fist of two people was found in Numa Creek, which quickly caused a boil throughout Alaska, and the news was also reported in the United States across Canada.
