You might find this interesting. Here is some metal detecting at abandoned mines in Cobalt, Ontario (Canada) and I cut a couple of the finds with a tile saw to expose the silver inside. I am pretty happy with these rocks.

What do you do with the rocks? They're beautiful. You mentioned polishing some. Do you polish the slabs? Reclaim the ore? Just curious. Don't have anything like that around here, but I did find a fairly large rock with a lot of magnetite (I think) in it. A magnet stuck to it and it reflected light like that when I cut it. I thought it might be a meteorite so I sent a sample to a collector, and he said it wasn't. Never thought about slabbing it and polishing it.

While searching for info on the use of a vibratory lap, I found a Utube segment of someone cutting an polishing silver ore with beautiful results. The drill was to polish one face of the ore lump and then use a tile saw to cut off a slab with one finished face.

Of course, now I also have to build a larger workshop, so I have room to work. Probably, a winter project as I spend most of my spare time during the nice weather rockhounding or exploring. |

In the video, did a goofy guy chew gum and put hockey cards on the shifting/spinning rocks in the vib. lap? If so, that would be me (meMiner). LOL |

I have collected, cut and polished magnetite/hematite and it think it polishes up rather nice. Mine is usually mixed in layers with jasper in the form of banded iron formation rocks. Hopefully, you kept that rock. I enjoy the hunt for silver. I have sold some (it helps with expenses), given away some and stacked up the rest. I have a friend who will try refining. He want the shavings in my saw. If it works out, I will probably get a kiln and try it myself. |

greig, what tile saw are you using?

No goofy guy was present , but I'm sure it was you. Nice job and very confidence building for others. Congratulations.

greig , what tile saw are you using? It is a Home Depot brand, with a 7" diamond blade (that the package said was good for porcelain tile). I wish I had a larger blade for larger rocks. A trim saw would make better cuts, but the darn things in the size I want are expensive... |

I got slagged pretty good by some fellows, who I guess just want to see the machine and rocks. Cannot please everybody... |

I am not sure what to do with the slices from this video. One answer is to polish them on a vibratory lap. As the host rock is dolomite/calcite, I am actually tempted to try etching the larger slice in muriatic to see if I can get clusters or wire silver from these samples. It might just destroy a perfectly good rock. If that happens, I know somebody who wants some silver to refine, so it would not be a complete waste. Open to ideas.

A trim saw would make better cuts, but the darn things in the size I want are expensive... I've been using an ancient 10" tile saw for pendants. Works as both a slab saw, up to 3 1/2", and as a trim saw as long as you have steady fingers. After I saw to a rough shape I use a flex tool for final shaping and smoothing. I just got an Agate Kutter blade from johnjsgems . Haven't tried it yet, but I anticipate smoother cuts than the tile blade is giving me. |
