Mining recruitment in Zimbabwe

bitcoin is tamper proof

last weekend, when CNBC's Deirdre Bosa was interviewed at the "money 20 / 20" event in Las Vegas, apple co-founder Steve Wozniak said he thought bitcoin was a better value standard than gold and the US dollar. He explained that the difference between the two is that the supply of bitcoin is limited, because it is estimated that only 21 million bitcoins can be mined. Unlike the dollar or any other legal tender, bitcoin is unlikely to be affected by the whims of influential bankers. On the other hand, no one knows how much gold there is in the world that can be mined at any time. In this sense, Wozniak said, gold is "a bit fake," while bitcoin is more "real and real."

before that, the price of bitcoin soared for several consecutive months, breaking the $6000 mark for the first time a few days ago. At present, the price of bitcoin has stabilized at about $5500, but we can expect that bitcoin will continue to show its real potential. That's why experts like Wozniak predict that this cryptocurrency may eventually replace gold as the standard of financial value - a view he thinks is quite attractive

more stable than gold

but is cryptocurrency number one really more stable? Yes, and No. Critics will say that it is prone to value volatility, making it quite unstable. However, as Tom Lee, co-founder of fundstrat global consultants, told business insider earlier, this volatility is predictable, and it is not unique to this cryptocurrency“ When people talk about the fluctuation of bitcoin today, they forget that when we leave the US dollar, the gold standard of the US dollar, the fluctuation of gold price in the past four years is similar to that of bitcoin today. "

crucially, Wozniak commented that bitcoin is easier to regulate than gold. He then compared the stability of bitcoin to owning a house“ Your house is valuable. " If it's a house now, 40 years from now, even if the price rises, the government will charge more taxes from it, and it's still a valuable house, "said the former Apple senior engineer, whose interest in cryptocurrency started just for fun

given all the volatility, the government and regulators continue to "test" the growing cryptocurrency market. Some have taken tougher measures to ban the cryptocurrency altogether. However, bitcoin still exists, and experts predict that the value of bitcoin will rise sharply in the next few months

In the mining instry, gold proction in Zimbabwe by minerals and mining companies affiliated with the UK is growing well. The drilling project in Ghana also achieved satisfactory results, and the drilling of diamonds and gold mines in Australia continued. In addition to developing its main core business in Hong Kong, HEC completed the Corvia power plant project in India in 1990; There are also new projects in Iran, Thailand and Indonesia, and we continue to focus on China's Likang power plant project

The legal mining behavior starts from exploration and survey, which is prior to the actual mining behavior in mining license, but small-scale ore mining has a certain impact on the environment

6.3.3.1 exploration and survey business

after obtaining mining license, explorers usually set up camp in the area with mining right. Typical prospecting and exploration involves indiscriminate excavation and, in some cases, trenching to determine the possible ore strike and type of geological structure. These caves are usually very narrow, only more than 5 meters deep, with a platform every 1.5 meters. These jobs are labor-intensive, using hammers, shovels, and trolleys to break the soil, move, and dispose of it. The excavated material is mped randomly in pits and ditches. A professional geologist usually catalogues these projects at the end of the permit period, and finally writes a geological report so that the mining application can be approved

6.3.3.2 mining

mining includes expanding and deepening the opening and shallow well, or re excavating a new opening to obtain ore. The use of self or employed earth moving devices, such as bulldozers, hoes and excavators, is common, especially for some minerals identified in the Ndola rural emerald reserve and the kalomo Amethyst area. Blasting is usually the last resort to solve the problem of hard rock. In addition to these works, groundwater should also be extracted in Ndola rural jadeite reserve. The water is pumped out from the bottom of the hole by a refueling pump. Where large heavy bulldozers are used, it may be particularly easy to proce a lot of garbage. Because of the desire to get the so-called gems and the idea of getting money faster, the rubbish is mped at will without any plan. This leads to the accumulation of garbage. Some openings may be only 1.5 meters shallow, such as in the kalomodo mountains; Some may be as deep as 70 meters, such as in Ndola rural emerald reserve, which is basically plain

6.3.3.3 mine closure

according to the mineral law, the owner of mining right should apply for mine closure before partial or total mine closure. It is necessary to confirm that all the explored and mined land has been restored, sorted, restored and afforested, and all the dangerous objects must be closed or isolated. Unfortunately, most of the sites are abandoned, and the hazards from the openings and other mining tunnels remain in place, often silting up soil and rain

6.3.3.4 mineral processing

the mining of small mines in Zambia is monopolized by four places: emerald in Ndola village, Amethyst in kalomo region, green jade in Chipata Lundazi region and green jade in petauke region. Gem processing includes washing, cutting, using such as pliers, awls, chisels, lenses, etc., through knocking, smashing to obtain fragments, color grading, remove the unwanted parts. Waste procts are often proced in the bottom and surface of the ore

6.3.3.5 environmental impact

some reports on the impact of small minerals in SADC field have been published. This method is used in many fields, such as field tour, reception and research-based literature. However, they lack tracking or analysis data to support the argument, and lack clear criteria to objectively consolidate the conclusion and be considered meaningful. These potential effects make these mineral mining may be classified as environmental impact, pollution impact, occupational health, socio-economic and cultural impact. These are:

first, environmental impact. Including the destruction of natural living environment in mineral areas and waste treatment sites; Destruction of the surrounding natural living environment caused by radiation and waste mping; The destruction of the surrounding natural living environment caused by the inflow of population; Changes of water body and ecology caused by sedimentation and change of flow path; Change of groundwater level; Ground subsidence caused by insufficient restoration and instability after pit closure; The risk of instability of buildings and dams, legacy equipment and buildings; Unprotected caves; Soil erosion, etc

in the review of environmental considerations in gem mining, V. malango stipulated that small-scale mining is not proportional to the impact on the environment. The impact of gem mining is the siltation of rivers, mainly because the miners have no experience and skills, resulting in erosion

p.m. Banda (1995) emphasized the environmental considerations e to instrial minerals in Zambia, such as use conflict, air pollution, water pollution, solid pollution management, ecological damage and socio-economic impact. Land use conflicts are attributed to radiation from blasting operations and Quarrying and crushing activities, as well as ground subsidence caused by mining and mping of soil for other uses by large earth moving trucks

indiscriminate excavation of laterite and stone has led to subsidence in Lusaka. The air pollution is attributed to the gas emission from blasting and crushing operations. These discharges affect the local population and ecology, especially the vegetation and soil. Major pollution examples are: Joint quarrying in Lusaka has led to air and noise pollution; Due to st emission, qilanga cement company has polluted the environment, resulting in the destruction of makulu mountain workstation; Air pollution in the form of st emissions from mindeco's grinding and crushing operations and the Lusaka limestone grinding plant

considering that waste management includes toxic substances in st effluents, especially on windy days. The environmental pressure of trees, fuel and soil around human beings leads to ecological destruction in the form of forest cutting and animal hunting. The social and economic effects make people immigrate and interrupt their family life to mine. When the mine is closed, unemployment and local supporting instries close down. Between July and August 1990, wolf felt completed a survey of 50 small mines and related instries in Zimbabwe and Zambia, and assessed the degree of environmental pollution caused by mining. The assessed impacts are: pollution of smoke, gas and st, hazardous substances and soil pollution

water pollution caused by discharge, minerals and mping lead to oil deposition and soil erosion

vegetation and wildlife damage caused by subsidence, deforestation, gas, river erosion and land use

direct health losses caused by toxic substances, noise and unprotected excavation
