testing a new pyramid mold with a silver pour.

Silver Smelt straight from the dried slimes from the silver stripping reactor. Worked great, but did make some smoke and fumes. We allowed the slimes (A mix of silver oxide, silver chloride, and metallic silver along with copper, nickel, and other contaminates.) to dry for over a day on a hot plate so that the silver would oxidize more.

The processing of 500lbs of gold ore into about 40lbs of concentrate. The ore we have has all the PGM's locked up between layers of pyrite, witch in turn is combined with iron ferrite (and other forms of iron) witch are magnetic. So all we do to get the pyrite out is collect the magnetic iron witch is attached to it. Then we wash the concentrate in HCl to remove most of the ferrite and open up the pours of the pyrite to help the leaching process work better. Original YT air date: 2021-09-06

Test of the magnetic separator. We are very happy with the magnets but the belt needs to be aligned where it will stay aligned witch means we need to rebuild the frame. The magnetic drum however works great. pulls all the magnetic sludge out of the ore grind from the ball mill. Then we will use an alkali leach on the magnetics (iron) to git out the platinum group metals.

A very simple and inexpensive home smelter using a propane gas torch with a air jet draw intake, and some special ceramic foam insolating blocks witch are not hard to find, and a long propane hose. just to be save. We were able to get it up to 2480 degrees farinhite on the first run. We could not really open it up because it was starting to blow backwards. We will plug the holes around the pipe with some special insolating rock wool to seal it up better. We still need hotter.

Testing a mini smelter for the first time. Can you tell? We added fare to much silica sand to the flux witch made it to thick and sticky, and by the color of the glass left behind some metal. We are learning.

Magnetic Separator Construction and Test. We are using dry concentrate here. It will normally run with wet ground ore from the ball mill. Needs a little alignment adjustment and a motor speed control / and or deferent pullies to slow it way down. will be adding things like a brush or squeegee at the end to brush off the wet concentrate.

Magnetic drum test 1. Test of the drum rotation.
