During 1890, 410,000 cubic yards of tailings, left by former workers, have been elevated by hydraulic nozzles to a height of about 60 feet. The yield was 1,478 ounces of gold, or an average value per cubic yard of 3d., while the cost in wages was 2,580, or about 1. per cubic yard, The system of raising washdirt is exceedingly interesting.

05/06/2018This calculation results in 1.39 * 10 9 kilograms of gold in the ocean. Using the conversion 1 kilogram = 0.0011 tons, we reach the conclusion that there are about 1.5 million tons of gold in the ocean (assuming a concentration of 1 part per trillion).

For estimating purpose one ton of gravel (pea gravel or 3/4″ stone) weighs around 2000 pounds a cubic yard of gravel equal as 3000 pounds, so ton to yards gravel such as 2000/ 3000 = 0.66 cubic yards. Therefore 2 tons to yards gravel such as 4000/3000= 1.33 yards. You Can Follow me on Facebookand Subscribe our YoutubeChannel ALSO READ :-
