has anyone tumbled bumblebee jasper? any tips or tricks? have been told the rock has different hardness and thats why it wont tumble well but the same guy said he had never tumbled any so he might not have been the right person to ask

Arsenic is really bad for you. People have used it to kill things for centuries. The OSHA action limit is 5 micrograms in a cubic meter of air (.005 ppm). We are talking fractions of a part per million. Do you really want to mess with something that toxic? How much do you think you breathe when you open the lid to your tumbler? OSHA says you are not allowed to eat, smoke, use chewing tobacco, chew gum or apply cosmetics in areas that exceed the limits. How much arsenic do you want in the rest of the stones in that tumble? Maybe someone would touch those stones and eat or drink without washing their hands. Arsenic is a metal so it stays around a long time so i would not recommend dumping it in the backyard. Sewage plant folks get really concerned when something kills off all the bacteria in their digester tanks. They start calling all kinds of environmental folks (my former job) to come and investigate.

I don't know what bumblebee Jasper is but given the responses it obviously must contain arsenic. I'm wondering, however, if it is in a form that is actually dangerous. It seems that if the rocks are safe to handle then the slurry from tumbling them might not be so bad? In other words, is it possible that the arsenic is still tied up in the compounds that make up the rock? I think that what is going on in the tumbler is a physical reaction and not a chemical reaction. It doesn't seem like arsenic metal will be coming out but instead just smaller particles of the arsenic bearing silicates that I would guess have reduced toxicity. I would love to hear from someone with more knowledge on the matter.

I would submit that even if there is arsenic in the slurry, if you were to use a filter it the way that rxscram did, and add some sort of permeable membrane at the top to capture the slurry, you would end up with water that is safe to dispose of and have slurry that is captive and could be dried out, bagged and disposed of in a landfill. Especially if you aggregated your slurry from other loads and put kitty litter in it. You would dilute the concentration significantly.*** forum.rocktumblinghobby.com/thread/76693/homemade-slurry-filter-large-pictures?page=1&scrollTo=891128***Disclaimer, this is all speculation on my part, and the LAST thing that I am is a chemist/scientist. I think that the charcoal and other filtering of the water would make it potable, but I wouldn't be willing to drink a glass of that water based on MY speculation. I try to be safety and environmentally conscious about not only my rock hobby, but life in general, but ignorance + good intentions does not necessarily = best practices. Take my comments with several grains of salt, and defer your decision until someone who knows WTH they're talking about weighs in. I would absolutely NOT mess around with rough grinding/cutting that stuff without heavy-duty throw-away gloves and a REAL respirator, and even then...

well i can appreciate everyone's concerns but as a science major i understand there is a difference between arsenic sulfide and arsenic i could not find a creditable or peer reviewed site with info on the dangers of working with this stone just a lay person who have an OPINION that this stuff is unsafe to work wit. if anyone has a link to share on the dangers that not just someones blog i would love to find more info on working this stone i think a lot of people see the word arsenic and get scared as long as i am not eating it and working the stone wet i feel the danger is small of course that just my opinion too

More theory and not proven fact: The arsenic should be bound pretty tightly in the rock (which would explain why Bumblebee Jasper can to bought and sold and is not regulated). Some arsenic may dissolve in the slurry so I would wear gloves while handling that and not dump the slurry anywhere. The arsenic should not evaporate and become air-born, only the water in the slurry will evaporate. If the dried slurry is dust like, it could be breathed in and absorbed by the body. If the slurry is cement-like, the arsenic should be trapped again and could be disposed of. So I would put the liquid slurry in a disposable container and then add cement mix, wait for it to dry and then dispose of it.

I do not believe there are any regulations on minerals. So using legality as proof of safety is not a good idea.
Go on eBay and see the the uranium and other scary stuff for retail purchase as proof of concept.
I dump slurry in my yard. Don't want arsenic sulfate in my soil. Soluble substances won't be filtered by a physical filter. Perhaps the carbon in Jeff's filter setup adsorbs it. I won't be tumbling bumblebee. But that is me. I'd love to see the finished product!!
Have fun!!

Have fun!! Good point. Legal definitely does not mean safe. However, there are certainly regulations on minerals. They may not apply to the individual. For example water companies monitor for any number of different minerals. (How accurate they are and if the regulations are appropriate is another question.) Or sometimes the disposal of the mineral is regulated but not ownership, like liquid mercury. Or sometimes you have to be specially licensed to buy it and sales are tracked. I am guessing the uranium you saw on eBay is an ore and it may not even be that radioactive. It certainly can't be used as is in a power plant or bomb. Still, I am certainly not buying any nor would I grind or tumble Bumblebee Jasper. Even something as innocuous as a tall ladder can be dangerous if you don't know what you are doing!

Bumblebee jasper is delicious and great for lawns.
