Is NING Hua Fu Li Cheng authentic

1. Shanghai also uses RMB, and the central bank has not released any currency issuing rights for the time being

2. mining: is to dig out the ore; Mineral processing: the excavated ore is washed and processed by some equipment to select what you need.

3. The purity of sand gold is very low, generally there will be no fake, because it is not worth money.

4.

Placer gold is a kind of gold which is washed by river and separated from quartz vein. Because this kind of gold is as fine as sand, it is called placer gold. Placer gold is easy to mine, while rock gold mining process is relatively complex and difficult. Generally, only one ton of ore can be mined to extract several grams of gold. There are two kinds of mining methods for placer gold deposits: open pit mining and underground mining

According to the characteristics of structure and the development of geotectonics, four metallogenic types with similar parameters can be divided. There are more than 3200 placer gold deposits, tens of thousands of placer gold mineralization points and heavy sand anomaly areas in China, which are distributed in 27 provinces (cities, autonomous regions), almost all over the country

mining method

1, gold dredger mining method

in the early 1960s, China's first gold dredger was built and put into operation, which opened the historical prelude of China's placer gold mining mechanization. At present, China's placer gold has basically realized mechanization. By 1989, there were more than 130 gold mining vessels of 33 types in China, which were used in more than 10 provinces (regions). The amount of gold mined by gold mining vessels accounted for more than 80% of placer gold proction

2. Construction machinery mining method refers to mining placer gold deposits by using mechanical shovel, bulldozer, scraper, loader and other construction machinery to excavate and load ore and rock, and using belt conveyor, truck scraper, loader and other transport machinery to transport ore and rock. It is suitable for use in arid areas such as Inner Mongolia, Sichuan, Gansu, Qinghai and Xinjiang. The following will introce bulldozer mining method, front-end loader mining method, scraper mining method and mechanical shovel mining method

Hydraulic mechanical mining method is a continuous proction process in which water gun, sand pump, water pump and other mechanical equipment are used, and the same water flow is used to complete flushing, transportation, washing and tailings disposal in turn

5. Take Metro Line 1 (Luobao line) to Laojie station, then transfer to Metro Line 3 (Longgang line) to Universiade station, and then transfer to m229 (Liuyue new village shuilanwan) to pass Longgang sports center or Universiade special line 14 (Longgang Sports Center - Universiade subway connecting station)

6. I'm from Nanjing. You take the subway at Nanjing South Station. To Nanjing railway station. Sit down and take a No.17 bus. You can find it. You can ask others where the No.17 bus terminal is. It's near the railway station.

bus line: South extension of Metro Line 1, the whole journey is about 4.8km

1. Walk about 90m from entrance 1a of jiahu metro station to jiahu station

2. Take South extension of Metro Line 1, pass 3 stops, and reach Tianyin Avenue Station

3. Walk about 290m to Hongfeng celebration exhibition in Nanjing...
