Mining Techniques of the Sierra Nevada and Gold Country

Hydraulic mining was a variation on ground sluicing where the water delivered to the site would be shot through a nozzle at high pressure onto the face of the cliff, thereby washing away tons of boulders, gravel, dirt, and gold. The first use of this method is credited to Edward Mattison in 1853.

Iron Ore Today's Spot Price & Charts Market Index

Iron Ore (Fe) is mined in around 50 countries worldwide and used to make steel (buildings, cars, white goods etc.). Global economic growth is the primary factor that drives its supply and demand. When economies are growing, the need for steel in construction increases which drives the price up.

Rock Crushing methods and How to recover gold from Ores

A heavy cylinder of iron is welded to a long rod and placed inside a pipe or tube which is just a bit larger than the diameter of the iron cylinder. This iron cylinder is picked up and dropped onto the ore, much in the manner of the old time stamp mills. This method seems to be popular in Australia.

Oct 05, 2016 The per cent of iron in the ore as mined must be not less than 50%, if it is to be used without being first improved (beneficiated) by cobbing, washing, calcining, or magnetic concentration. Leaner ore is found in very large quantities; and in a favorable situation, it may be workable by some concentrating process.

Sep 10, 2015 Washing and classifying of aggregate can be considered in two parts, depending on the size range of material. Coarse material: Generally above 3/8 in. (sometimes split at 1/4 in. or #4 mesh). In the washing process it usually is desired to remove foreign, objectionable material, including fine particles. Fine aggregate: From 3/8 in. and smaller.
