Rock Crushing methods and How to recover gold from Ores
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. A more expensive but certainly faster and easier method is to use a small jaw crusher, such as is used in preparing samples for assaying.
Metallic iron is mainly formed through gas–solid reduction, approximately 2/3 through indirect reduction and 1/3 through direct reduction. Carburization of iron can start at relatively low temperatures in contact with CO gas. Dissolution of carbon in solid iron or sponge lowers the melting point of iron significantly.
Crushing in Mineral Processing
· Typical hard-rock crushers like jaw, gyratory and cones break rock by nipping the ore between a fixed/stationary and a moveable wear-resistant surface/liner. How much reduction each crushing stage is capable of infliction of rocks (reduction ratio) is driven by the angles between the 2 surfaces on each side and holding the rocks-to-be-crushed as the move towards and away from each …
