how do i get manganese metal from manganese dioxide?

I have a very large amount of manganese dioxide, which i wish to turn into manganese metal, however, i have a problem with reducing it with carbon, which is that i dont have a furnace, or even the materials for a makeshift one, as i found out all the bricks that are sold in this state, are all sand or cement, no clay, not even at the hardware store.

I was wondering, if there is any way for me to get manganese metal other than reducing with carbon, such as electrolysis of manganese in some soluble form.

There are recipes on the web for inexpensive homemade castable refractory material.  Most use furnace cement--bought by the pint or quart in most larger hardware/bigbox stores--- and perlite.

One might start out with a large-coffee-can-sized furnace to test the concept, after which a larger furnace could be more confidently constructed.

you can react the manganese dioxide with HCl and you wil get manganese cloride then and aluminium foil and you will get manganese metal and aluminium cloride.

Ask for "Firebrick", not standard brick.

no you dont understand, they dont even sell any clay or ceramic bricks, ive been searching for ages for firebricks, but right now, the only ones i can find cost $30 a brick.

I dont know why, but all bricks here are cement and sand, no places use other bricks, no stores here sell other ypes of bricks, i looked into it, i looked into firebricks a while ago when i needed something for the refractory for an arc furnace.

i wish they even had standard brick here, but alas they dont, and all the cement/sand bricks they have here explode when heated, as do paving bricks.

So until a time where i can get some damn decent bricks, is there another way to get manganese metal?
Buy in a bag of "castable refractory" - potters use it.
Find out what they line the firebox of a fireplace with and use that. You can use cement bricks if you heat them over and over slowly to bake out the moisture. But they won't last too long used in an oven. But if dried right they won't explode.

i know of all these things, but for me would cost hundreds to aquire. Also here they dont sell fireplace supplies of any kind, since nobody has a fireplace, nor could possibly need one, since the heat is a constant 30+ and humudity always over 50%
