Effective Recycling Methods for Rare Earth Metals

Researchers are rummaging for newfound alternatives to commonly used rare earth metals found in everything from solar panels, wind turbines, and car batteries. The metals are rapidly decreasing in quantity. Thus, resulting in researchers aiming to develop effective recycling methods to supply the rapid growing demand for the metals, before they further hinder the growth of renewable energy technologies. To enhance the energy saving capabilities of technology, expensive and rare earth metals are required. The ongoing issue of the rare metal shortage sprouted from a trade halt in China. Thus, the Critical Materials Institute, directed by Alex King, was established to enhance supply chains, and develop alternative materials that are free from the use of critical elements that are difficult to obtain. One solution for metals that are expected to decrease in the long run is to improve recycling habits. About less than 1% of rare earth metals are recovered, due to the extreme difficulty of retrieving the metals from complex technology. However, various companies including Umicore and Honda are developing recycling programs, ranging from melting magnets to tease rare metals out, to recovering metals from rechargeable metal hydride batteries. For elements where an increased demand is expected, a viable solution is to open new mines. The rare-earth division of Mountain Pass mine reopened, and has about 450 potential rare earth mines to examine. Alex King says that making the mining process more efficient will aid in increasing the amount of materials collected. His institute utilizes DOE supercomputers. Mining companies often grind up rock, throw it into water, and blow bubbles through it causing the rare earth minerals to float to the top. The supercomputers search for molecules that bind to the elements to help them float, capturing up to 75% percent of the materials. King says, the approaches are intended to be utilized within the next couple of years. In my opinion I find the decreasing rate of rare earth metals to be troublesome. The planet is presently in desperate need of efficient renewable energy technologies, and starved of the necessary materials, developing green technology is practically impossible. I personally believe the Earth has suffered severe damage, brought upon by society's creation of pollution, toxic chemicals, and other hazards. Hence, together we as a society ought to become more environmentally conscience and utilize technology in a manner that will salvage our planet, instead of killing it. To utilize green technology efficiently, we require the rare earth metals.
