I have to do a science project and i need to know how dolomite and sodium carbonate are extracted from the earth. 10 pts to the first good answer.
Dolomite - calcium manesium carbonate occurs as large rocky deposits in mountain ranges consisting of many millions of tons of dolomite. It is usually mined by explosives which break up the dolomite and then it is crushed into workable pieces. Just basic open cast mining Sodium carbonate exists as large pans which are the dried up remains of lakes. The sodium carboate is harvested by excavators, and purified by dissolving in water, filtration to remove impurities and recrystalisation. Also very basic open cast mining,
I would stop at 2nd, though. If you're going too fast and you go to 1st, it might throw you off.
im not sure if a dirtbike is the same as a street bike but on the dirtbike i usaully just ease off the throttle hold the clutch in and apply the brake when at the stop sign or red light.but you should probably wait for a person who rides a street bike to answer.i tried to help sorry if it didnt help
a shovel haha .it can be extracted from the ashes of many plants.
