Low carbon development will stimulate the growth of related mineral demand

The World Bank recently issued a report entitled “minerals and metals will play an increasingly important role in the future of low-carbon development”. The report believes that the clean energy transformation will stimulate the growth of related minerals and metals, including aluminum, copper, lead, lithium, manganese, nickel, silver, iron and steel, zinc and rare earth minerals (indium, molybdenum and neodymium).
The signing of the Paris agreement in 2015 shows that the world has embarked on a significant development model for reducing greenhouse gas emissions. One hypothesis is that the development and use of non renewable resources in the future may be reduced in the context of carbon emission constraints. The report is in the above assumptions under the framework, the key to determine the future of mineral products and to predict the reserves and yield level of worldwide metal, pays attention to the impact on developing countries with abundant resources, at the same time, blank key research and future work are proposed.
First, low carbon development will stimulate the growth of mineral demand.
The world bank and the international mining and Metals Association (ICMM) jointly to transition to a low carbon future demand for metals are analysed, using the analysis of the International Energy Agency (IEA) of the “energy outlook to meet the effect of 2 C and 4 C and 6 C global warming targets 3 scenarios of renewable energy technology deployment in 2016”. In the global warming of 6 degrees, renewable energy power generation (including hydropower and biomass) in the energy structure of the proportion from the current 14% to 18%, while the global warming of 2 degrees, as high as 44%.
The precise prediction of the demand for metals is at least determined by 2 independent variables: the determination of the international community’s successful long-term climate goals in Paris and the selected technological lines. Not only should we specify how many wind turbines, solar panels and low emission vehicles should be deployed, but also what technologies will be used for wind and solar energy, as well as what are the leading zero / low emission vehicles. For example, the 3 main forms of new energy vehicles – electric, hybrid and hydrogen, each electric car demand for the metal is not the same: electric cars need lithium; hybrid cars use lead; a hydrogen powered vehicle using platinum.
Research shows that the global warming between 4 and 2 temperatures, the demand for low carbon technology related metal demand rapidly increased. The most obvious example is the electric vehicle battery, including metal aluminum, cobalt, iron, lead, lithium, manganese and nickel, its demand in the global warming scenario in 4 degrees is relatively low, while in the 2 C global warming scenario, the demand growth rate of more than 10 times.
The requirements for related minerals are as follows:
In the global warming 2 degrees of the scene, as of 2050, total aluminum demand will exceed 80 million tons, the cumulative demand for chromium will be close to 4 million tons, the cumulative demand for cobalt is about 90 thousand tons, the cumulative demand for copper will reach 20 million tons, the cumulative demand for indium is about 25 thousand tons, the cumulative demand the lithium is about 20 million tons, the cumulative demand for neodymium will exceed 120 thousand tons.

Membrane technology, why make gold membrane become the industry veteran?”

In the just concluded recently with “responsibility and mission of green technology, ecological mining” as the theme of the 2017 Chinese international gold mining technology forum, Zhaojin film days have attracted much attention because of its strong advantage in the field of membrane technology. Membrane technology and the golden film days why so much attention? What is the emerging technology of membrane technology? What are the rich and powerful genes in the field?
Water is the source of life. Facing the shortage of water resources and serious water pollution, how to realize the zero discharge of wastewater and the recycling of water resources? Separation membrane technology, as a mature industrial technology, is showing its talents.
Some people say that membrane technology is bringing people into an era of renewal. Membrane is a material with selective separation function. Membrane separation is the process of separating, purifying and concentrating the different components of the liquid by selective separation of the membrane. Membrane is the core of membrane technology. The properties and chemical structure of membrane materials play a decisive role in membrane separation. At present, membrane technology, as a new separation technology, has been widely used in gas separation, material separation and water treatment, in which the demand for membrane products is the largest in water treatment field.
In the field of water treatment, membrane separation technology with its high efficiency, low energy consumption, simple process, convenient operation, no pollution, easy amplification, combined with other technology integration and other advantages, to promote industrial development, improve the living environment of mankind, to improve the quality of life of the people of common technology, replacing the various traditional water treatment methods, become in twenty-first Century the mainstream water treatment mode.
According to China Film Industry Association statistics, in recent years, China’s membrane separation market has maintained an average annual growth rate of more than 25%, membrane technology, water treatment market growth in space is enormous. According to market analysis and prediction, the next 10 years, China’s membrane water treatment market will be 40% annual growth rate of rapid development, membrane manufacturing industry annual growth rate will be more than 20%, much higher than the international level. The application of water treatment accounts for about 85% of the domestic membrane separation market, and the individual processing capacity has reached 50 thousand to 100 thousand cubic meters / day, and the amount of the individual project contract is over 100 million yuan.
It can be said that as a strategic emerging industry, membrane technology is playing an increasingly important role in energy saving, environmental protection, petroleum and chemical, coal chemical, energy and other fields. The scale of engineering application of ultrafiltration and microfiltration and reverse osmosis membrane technology in energy and power, non-ferrous metallurgy, desalination, water treatment, water reuse and other areas to expand rapidly, a large membrane water supply project, the landmark wastewater reuse project and desalination projects have been completed.
The development of membrane technology is the result of both market demand and industrial policy. In China vigorously promote the construction of ecological civilization, the current industrial economy to adjust the structure to the way the industrial separation membrane are also some new features: film industry development to the low cost and high performance, green direction; membrane technology for drinking water safety, reduce environmental pollution was significantly increased; membrane technology to upgrade energy saving and emission reduction, the industrial structure is becoming more and more obvious role in promoting the rapid development of the market; the membrane material, and downstream industries more closely.
