Olivine: The Carbon Eater
Olivine: The Carbon Eater. Due to plate tectonics, a mineral comes from inside the earth which traps carbon dioxide into it from atmosphere. When hot molten rock crystallizes and solidified into igneous rocks, these pure minerals are found in it. We can also found it as fragments at Papakolea Beach of Hawai, Talofofo of Guam, Punta Cormorant of

How Gold Is Mined | Gold Mining Process | World Gold Council
The lifecycle of a gold mine. People in hard hats working underground is what often comes to mind when thinking about how gold is mined. Yet mining the ore is just one stage in a long and complex gold mining process. Long before any gold can be extracted, significant exploration and development needs to take place, both to determine, as accurately as possible, the size of the deposit as well

Olivine can reverse climate change and ocean acidificaiton. It is rare to come across a solution to lowering the amount of CO2 in the atmosphere that is simple, yet plausible, and which can be started right away with no new science.

Places Where Olivine Can Be Found
Ancient olivine most likely came from the Red Sea island of St. John. The first source of olivine was discovered on the Egyptian island Zabargad. The stone became so popular over the years that a Roman historian wrote about it in year 50 AD. At that time, the Egyptians had already been mining it for thousands of years.

Olivine: The Environmentally “Green” Solution to Climate
Perhaps it is impractical to mine olivine for the sole purpose of carbon sequestration, but olivine could be a byproduct of other mining ventures. If olivine is a byproduct, then there is no increase in carbon emissions to take it out of the ground and this could make it a viable solution, but this is still very speculative science.

Olivine: A rock-forming mineral. Used as the gemstone peridot.
Olivine is the name of a group of rock-forming minerals that are typically found in mafic and ultramafic igneous rocks such as basalt, gabbro, dunite, diabase, and peridotite. They are usually green in color and have compositions that typically range between Mg 2 SiO 4 and Fe 2 SiO 4. Many people are familiar with olivine because it is the

Olivine is a common rock-forming mineral in mafic and ultramafic igneous rocks, but it also occurs in impure metamorphosed carbonate rocks (picture below). It is a very common mineral in the mantle. Some xenoliths from the mantle are almost entirely composed of this mineral. Such a rock type is known as dunite.

Project Vesta / Home
Naturally, rainfall erodes volcanic rock, drawing olivine into the oceans. Through the natural process of weathering, rocks are transported through waterways and into the ocean, where, as part of the long-term carbon cycle, trillions of tonnes of CO 2 are permanently stored in rock. This process takes place over 100-200 million years.

Pushing the Price of Olivine Down
The actual cost of mining and milling the rock is only about $7/ton and transport is only $3/ton, so it is possible to bring the price per olivine ton spread on a beach to $10 per ton. So with 1.25 tons of CO2 removed for each 1 ton of olivine weathered, the cost per ton of CO2 removed from the atmosphere can be less than $10/ton.
