Operation Instructions

One of the most essential things to put in effect in a placer operation like the one described, is to never tolerate the water to go above the rag plant when the feed has been shut off. The water by itself, with no lacer material going above the rag plant, will wash a large quantity of the free gold and it will be lost. Once opening the operation the same thing must be produce. Create the feed and water at the same time so that the gold on the carpets will be confined by the placer material in the water. The carpets must be cleaned and the nap on the carpets not covered, so that the free gold can be caught in the nap and the finer gold go into the carpets. Sand and iron build up on the carpet (like a sand bar).

With the right quantity of feed , the right quantity of water and the exact pitch , or slope ,on the rag plant , all of the sand and iron will be stirring down the rag plant and the gold will be caught in the carpet (with a small sum of iron) when the carpets are cleaned. All of the above must be made in the field on a trial and error basis, until all 3 conditions are right.

A first point could be 1 ¼ “grade to each foot on the rag plant, then regulate up or done until the best form is found. Water and feed are set the same way until best results are getting.

Once these results are acquired, a good smooth operation can be keep.

The feed bin should be large enough to guarantee a stable and even feed to the screen with enough cushion so that at least a half bin is preserve among truck loads ( or however placer material is handle) from pit to feed bin. There are quite a few types of feeders that can be used the most common being a conveyor belt type with a gear head motor to move belt very slowly so that the feed is fairly deep on the belt . An adjustable steel gate on the bin at feeder helps adjust to an even feed. It is very main an even and constant feed be preserve so that the right quantity of water can be held at a steady rate. Also when the right amount of feed, plus the right amount of water is maintained, the exact pitch (or slope) of the rag plant can be set. Witch all 3 of these conditions in control the gold should settle in the carpet or the rag plant, and the sand and almost all of the black iron will go to tail and be eliminated.
