DOE Efforts to Extract Critical Minerals and Rare Earth Elements from Coal Sources

The US Department of Energy's (DOE) Office of Fossil Energy selected 13 projects to develop conceptual designs for commercially viable technologies for extracting rare earth elements (REEs) from coal sources and coal by-products. Each project will receive funding of up to $150,000 from the DOE. The conceptual design will include the system configuration, equipment characteristics, performance characteristics, and associated costs for systems that produce at least 1-3 metric tons per day of mixed rare earth oxides or rare earth salts and other critical minerals in some designs.

Demand for rare-earth elements, which include the lanthanides plus scandium and yttrium, has ticked upward over the past few decades. The long list of high-tech products that rely on rare earth elements includes cell phones, flat-screen TVs, electric cars, wind turbines, satellites, Tungsten Carbide Rods Single Hole defense aircraft, and high-performance magnets.

A secure, reliable, and sustainable domestic supply of critical materials and REEs are essential to the continued health of the Nation's energy and electronics industries and is an important contributor to national security. The Critical Minerals Sustainability Program of the DOE has demonstrated the technical feasibility of extracting these resources from coal-based materials. The project has entered laboratory-scale and engineering-scale prototype material processing to meet the expanding challenges and opportunities. The selected projects will accelerate the development of these commercially viable technologies.

The US coal industry is facing tough times. Demand for coal sources is dwindling, and the industry is under customized tungsten carbide fire for polluting streams and rivers with coal ash and acid mine drainage. But in that waste, and in some cases in the coal itself, are valuable rare-earth elements that may be readily recovered. If researchers can figure out how to extract them economically, sales of rare earths could help pay for some of the cleanup costs.

The conceptual designs of each project include an option for up to a $2 million feasibility study. This study will support an Association for the Advancement of Cost Engineering Class 4 cost estimate on the conceptual facilities that are capable of producing at least 1-3 metric tons per day of a minimum of 75 percent mixed REOs or RESs by weight and other CMs in some designs.

The research includes characterization of coal and coal by-products - including coal ash Tungsten Carbide Rods Double Holes from power generation, refuse rock from coal preparation plants, acid mine drainage treatment sludge, and young lignitic coal from North Dakota - so that recovery efforts can focus on coal-based materials with the highest concentrations of rare earths. The projects involve optimizing the separation and extraction of rare earths from various coal-related materials.

Even though coal ash is more concentrated in rare earth elements than coal sources itself, the rare earths it contains are tightly bound in a glassy matrix. Pulling those elements out of the ash requires a combination of physical and chemical processes. The research team uses washing and other physical methods to separate unwanted materials from the ash and prepare it for further processing. And then subjects the resulting ash, which is enriched in rare earths, to several chemical processing steps.

Terbium Oxide Price - February 24, 2021

Rare earth market quotation in China: cerium oxide, lanthanum oxide and terbium oxide prices tungsten carbide burrs continue to rise on February 24, 2021 under the gradual recovery of the global market. However, as downstream buyers do not accept high prices, new increased orders are limited. 

From the demand side, driven by the expected positive development of downstream emerging industries such as wind power, new energy vehicles, 5G equipment, and new infrastructure, the demand for rare earth functional materials is expected to increase significantly. Therefore, the first batch of total rare earth indicators this year Increased by nearly 30%, but it is still difficult to alleviate the current tight supply of some products. 

From the supply side, as the time for the National Two Sessions is approaching, customized tungsten carbide environmental protection efforts have also increased, which is not conducive to the release of production capacity of rare earth smelting enterprises, coupled with geopolitical instability in countries around the world, domestic rare earth imports are subject to certain restrictions, which is more conducive to the increase in market prices.

In the news: rare earth permanent magnet materials have been widely used in many fields such as aerospace, computers, communications, oil exploration, electric vehicles, etc. According to estimates, domestic demand will reach 450,000 tons per year by 2030.

China Rare Earth Price - February 20, 2021

China rare earth price continues its upward trend in late February, 2021 after the holiday of the Spring Festival, benefiting resonance of fundamentals, market and policy. 

From the supply side, due to the holiday, most rare earth smelting companies have reduced their production capacity. Superimposed on the Myanmar coup has affected the country’s export volume of rare earth products to a certain extent, so that suppliers’ confidence in price increases has continued to increase. 

From the demand side, under the situation that the development of new energy vehicles, wind power generation, electronic equipment and other industries is expected to improve, the tungsten carbide burrs blank amount of rare earths used by magnetic companies is still large, which is the main reason for supporting the upward adjustment of nonstandard tungsten carbide rods the quotations of the holders; from the policy side, the recently promulgated "Export Control Law" and "Rare Earth Management Regulations" are conducive to the warming of the market.

In the news: in 2020, the nation's new installed capacity of power sources will be 190.87 million kilowatts, including 13.23 million kilowatts of hydropower, 71.67 million kilowatts of wind power, and 48.2 million kilowatts of solar power, according to data from the National Energy Administration.

China Molybdenum Oxide Price

China molybdenum price is in the upward trend on February 20, 2021 after the holiday of Spring Festival. Driven by the continuous rise in international molybdenum price, domestic molybdenum chemical companies have strong rised mentality. 

At present, molybdenum concentrate price is above RMB 110,000/ton, molybdenum oxide price is advancing towards solid tungsten carbide rods RMB 1,660/ton. However, affected by the end of the Spring Festival holiday, traders' enthusiasm for entering the market has not yet reached the best state, so the atmosphere of buying and selling in the market is not good.

In the news: in January, factory prices for industrial producers nationwide rose 0.3% year-on-year and 1.0% month-on-month; purchasing prices for industrial producers rose 0.9% year-on-year and 1.4% month-on-month, according to data from nonstandard tungsten carbide rods the National Bureau of Statistics.
