Any tips on how to deal with cassiterite?

mfdes,
I am not to sure how much gravels you would like to process at a time. I myself use a Banjo box to do my gold and tin prospecting. Don't confuse this with a high banker banjo this is all manually operated. The beauty about the Banjo is that black sands, garnet sands and including cassiterite are your allies not your menace. The Banjo box can catch fine gold uses very little water, highly portable, cheap to make, classifies and washes large volumes of gravel compared to other non motorized equipment. The Banjo box was the favorite tool for the gold and tin miners in North Queensland. Not many people know about the old Banjo box and how it is operated correctly. A mate of mine is nearly 90 years old and he showed me how to operate the banjo correctly. Its easy to make with a sheet of ply wood and the grizzley you can fold up from some tin. I was thinking of taking some pictures of the banjo box and hints on operation and setup. If people are real interested i might do a build along.

Roscoe we'd love some pics and info on your banjo.
We are all here to learn.

I am interested Roscoe, I would love to make one.. I am still to start my rocker box, but if a Banjo is better, I will go with that..

Cheers, Tone

Ok, I have decided this week i will build one and take pictures of its construction, a friend want's me to make him one. This will be good as i can show you me making it, measurements etc. Then i will set it up and show the correct operation of it. I will do that this week, i will go gets some ply and materials.

The Banjo box doesn't rely on riffles to trap its gold. It relies on the operator, The Banjoer to drop water into the box very similiar to an ocean wave coming up the beach. The heavies will drop down to the bottom of the box and unite together forming a pack. As the wave comes in it cleans the bottom half of the box pushing any heavies that want to stick there head out back into the back of the box. The light material then washes out over the end riffle. The end riffle is more like a regulator and if any gold does sneak past you then it will be stopped by the gravel bar that forms behind the bottom riffle. The grizzley is quiet long at the end of the box, this is so that you can load it up with plenty of gravels and wash them down as required. The way you drop the water into the box is the key to the Banjo and it has very little fall compared to highbankers. Don't worry i will show all of this stuff. I will post next week in DIY projects.
