Ore mining
It depends on the source of the mine. If it is an "open pit mine", the investment is relatively small. The main investment is the wages of workers and the cost of transportation road construction. If the ore is deeply buried, the investment needs to be larger. In addition, the acquisition of mining license is also a part of the investment, and this is the main part. If there is no mining license, the others are always empty
To sum up, the main investment costs are as follows:1, workers' wages
2, machinery and equipment
3, transportation road construction and maintenance costs
4, mining license fees
5, and other costs
The following proceres are required to set up a gravel plant:
1. To set up a regular sand making plant, the instrial and commercial department must go through the national instrial and commercial department, apply for the business license and tax registration certificate, and provide the relevant information such as the certificate, registration cost, operation period, project name and application form of the sand making plant
2. The Bureau of land and resources shall examine and approve and set up a mining license
In recent years, the state attaches great importance to environmental protection, and the supervision of environmental protection is very strict all over the country. Therefore, the establishment of sand making plant must be approved by the State Administration of safety, and also through the environmental protection evaluation of the Environmental Protection Bureau. Here, we suggest that when purchasing sand making equipment, we must consider the environmental protection of the equipment, whether to configure st removal equipment or sewage treatment equipment, etc 
after the certificate is completed, it is necessary to go through the EIA proceres of machine-made sand. The specific EIA proceres are as follows:
< H2 > II. Process flow of machine-made sand EIA1. Project approval: firstly, prepare the sand making project documents and file them with the local economic development bureau
2. EIA: go to the local environmental protection bureau for environmental assessment after filing
3. The cost of signing the contract depends on the amount of investment
4. For the on-site assessment of environmental protection agencies, the EIA contents include materials, project equipment, materials and auxiliary materials, and the monitoring of surrounding environment (air, noise, odor concentration, etc.). Generally, the frequency of EIA testing is 4 times a day, a total of 7 days, and the enterprises also need to carry out household survey on surrounding residents or units
5. After getting the household questionnaire, the EIA agency will go to the surrounding residents and units to carry out household survey
6. After the investigation, the project was put into operation and applied for environmental protection acceptance
when you say to buy the mining right of a mine, do you mean that people already have the mining right and buy it from others? That's all you need to do
if it's a new application, you need to find out where the jurisdiction of the mining right of the limestone mine in your area is. Some areas have jurisdiction in the county, and you can apply through the county, but some areas have jurisdiction in the city or province, which is different
as for the topographic and geological map, if the geological survey work has been done in this area, it can be obtained from the local geological department. If the detailed exploration work has not been done, then only the regional survey data can be obtained. Geological prospecting is done by the local geological team or exploration company, and the evaluation is carried out by a special mine evaluation company, but it is mostly used for mine bidding, auction and hanging
what you said is too vague. Many of them can't be answered. I'm in this instry, and specific problems need to be solved
ha ha, let's give a detailed answer. It's impossible to buy mining rights from the local town government. According to my understanding of more than 10 provinces in China, the lowest mining right management organization is the County Land Bureau. As for the procere, generally speaking, it is OK, but it is not so complicated. If you look for topographic and geological maps, generally only the local geological team can have them, that is, the geological team that does the regional survey work in your area, and the local land department should also have them. But now many land departments are lost, so it depends on your luck. If you don't have a topographic map, you can find it in the local area: for example, the forestry bureau, the Agriculture Bureau and the land and Resources Bureau should have it. Use the 1:10000 topographic map to find the local regional geological map, preferably the 1:50000 regional geological map, and record the geological conditions. If the local government is not strict with these management, it should be able to pass. As for the delineation scope, we can use handheld GPS to find a geological expert. The key to applying for mining right is to have geological exploration report and project feasibility study report.
