The first night I filled one of the liners with 60lbs of multi-purpose sand more dense than play sand and the other one with 120lbs. 60lbs is good for a lot of movementsswings 120lbs starts to get quite heavy to carry aroundpress and both liners together 180lbs was a little ridiculous.

In Mineral Processing Design and Operations Second Edition 2016. Magnetite Fe 3 O 4. Magnetite is often contaminated with titanium forming minerals like ilmenite. The contaminated mineral shows an appreciable degree of magnetism. This property is made use of in the separation of ilmenite from other economical minerals such as rutile monazite zircon leucoxene in Western Australia .

In 2014 mines in the United States produced 57.5 million metric tons of iron ore with an estimated value of 5.1 billion. Iron mining in the United States is estimated to have accounted for 2 of the worlds iron ore output. In the United States there are twelve iron ore mines with nine being open pit mines and three being reclamation operations.
