The elaborate workings depicted in the above 1860s photo from montgomery, colorado illustrate how it wasn't long before the arrastra was incorporated into much more complex mining operations These recycling stats show the severity of the problem and the importance of recycling. The arrastra pictured seems to show a horizontal water wheel

While photos of this type are rare, the design is mentioned in mining journals from the 1800s.

The arrastra was a primitive crusher/mill used in old time mining operations It was horse/mule powered and used the action of grindstones to process the rock extracted from gold mining. Arrastras an arrastra, also known as a mexican rastra, was a primitive method used by early miners to process gold and silver ores It was introduced to the new world by the spanish in the 1500's

They were used throughout the world, often at remote locations where other processing methods were not feasible. In western north america during 19thand 20thcentu­ ries, lined circular depressions were used to reduce ores by gyratory crushing These 'arrastras' represent primitive but effective millingmethods and are found in historic mining districts as nodes in economic and resource exploitation patterns An arrastra was a crude powered crusher which goes back to the mining days of the spanish

Mules, burros or oxen were used to pull a heavy rock around and around to crush the ore

The crushed material is then mixed with water to create a. They were made out of local materials at little cost and were very efficient in crushing ore A shallow pit was excavated and then lined with fitted stones on the bottom and sides A drag stone was fitted with eyebolts from which it was dragged.

Mules, burros or oxen were used to pull a heavy rock around and around to crush the ore. In western north america during 19th and 20th centuries, lined circular depressions were used to reduce ores by gyratory crushing These 'arrastras' represent primitive but effective milling methods and are found in historic mining districts as nodes in economic and resource exploitation patterns Discover the shocking truth about food waste in the uk
