how to separate gold from silica sand

Can anyone help me in removing the iron oxide (approx 2%) from silica sand?

There is no way to get the same sand without FeO-contaminants from a polluted sand. You will not get rid of these 2% iron oxide without reducing the size of the sand grains. Only after finely

Heavy Minerals

Heavy minerals including gold on a gold pan. This concentrate is panned from river sediments in Lapland, Finland. It is very uncomfortable to do if only one grain out of one hundred or less is what we are looking for. We therefore seek methods to somehow separate heavy minerals from the bulk of the sand.

How to Make Flux for Gold Refining | Our Pastimes

You can make flux for gold refining by first obtaining all of the ingredients and then mixing them together in the proper portions. Measure and weigh 5 oz. of anhydrous borax using the digital scale. Measure and weigh 40 oz. of silica sand #70. Measure and weigh 10 oz. of sodium carbonate or soda ash. This will be the oxidizer for the flux.

Gold Recovery And How To Choose The Right Process + Infographic

Gold deposits can be grouped into two primary classes: placer deposits, where the gold is exposed from weathering and erosion, and hard rock, where the gold is still trapped within the host rock. Gold recovery methods for these two types of deposits vary greatly from simple panning to a complex network of grinding, chemical leaching, gravity concentration and more.

Reverse flotation of hematite from a local silica sand ore has been investigated using a batch, bench-scale mechanical flotation cell. The effects of various operating parameters such as type and concentration of collectors, type of acid, pH, conditioning time, solid-in-pulp concentration, particle size and temperature have been studied on the hematite removal efficiency by reverse flotation.

I discussed your question with one of my process colleagues in order to get his input on separation of gold from black sands. It can be difficult to get a good separation as the black sands are quite dense. This is even more apparent when dealing with coarse sand and fine gold. I believe the i150 will be setup to run at a maximum speed of 50Hz.
