Not So "Green" Technology: The Complicated Legacy of Rare Earth Mining

Aug 12, 2021For every ton of rare earth produced, the mining process yields 13kg of dust, 9,600-12,000 cubic meters of waste gas, 75 cubic meters of wastewater, and one ton of radioactive residue. This stems from the fact that rare earth element ores have metals that, when mixed with leaching pond chemicals, contaminate air, water, and soil.

Iron cycle - Wikipedia

Remineralization occurs when the sinking phytoplankton are degraded by zooplankton and bacteria. Upwelling recycles iron and causes higher deep water iron concentrations. On average there is 0.07±0.04 nmol Fe kg −1 at the surface (<200 m) and 0.76±0.25 nmol Fe kg −1 at depth (>500 m). [21]

Earth's Temperature in Past 18,000 years:

Small carvings of human females appear from Europe through Asia. The climate begins to warm. Advance of glaciers stops, and sea levels begin to rise. Flooding over vast areas of the earth intensifies. Development of reliable ocean navigation opened up the world around. Mini Ice Age lasts a few hundred years.

They are formed when an asteroid or comet strikes the surface. The tremendous amount of energy that is released in such an impact digs a big hole in the ground, and also crushes a huge amount of rock under the point of impact. Some of this crushed material is thrown far from the crater and then falls to the surface, forming the rays.

When you see it settling on the bottom and no more dissolves, you've reached the saturation point. The water has absorbed all the sugar it can. This condition is called super-saturation. Next, bring the pot to boil. At boiling, the saturation level changes. The solution is no longer super-saturated. You can now add considerably more sugar.

The processes involved in heavy metals partitioning between solid and liquid phases are dependent on the pH of the soil suspensions. At acidic pH values, heavy metals become mobile and adsorption onto soil particles becomes less effective16.

They are called "porphyry" because upper crustal stocks are typically porphyritic in texture, the result of a two-stage cooling process. Metal enrichment results in part from convection of groundwater related to the heat of the stock, and also from metal-rich hot water expelled by the cooling magma (Figure 20.6).
