Hey guys.
My name is Jason from Mt. Baker Mining & Metals.
Today we are going to run this sample of ferrochrome and a company from the UK sent us this stuff
and I think this is stuff they skim off of their pots, it's kind of a slag product and
there's some silica and there's some ferrous stuff still mixed in there.
And they want to crush it up and concentrate out the ferrous and get rid of the silica
so they can have the ferrous and re-melt it down into product.
So because it's so fine we're going to run it through our ore system, starting with the
conveyor module here down into the magnetic feeder, up the conveyor belt behind me into
our 16" x 12" Hammer Mill, currently it has a .8mm slot so we are going to grind all that
stuff up pretty fine we are going to run it wet to keep the dust down, come down onto
the Shaker Table, the iron and heavy material is going to come across the Shaker Table into
ports 1, 2, and 3, because we have so much volume that is iron it's going to be pretty
dense, the silica we are going to try and split off with the splitter here, down into
the spiral classifier, we are going to de-water the silica and capture that and then only
the very very fine stuff is going to go into our tailings pond and we can reciculate the
water.
So let's get it fired up and we will see how it goes.
So here's the results from our ferrosilica test and there's actually quite a bit of steel in that stuff or Iron
I guess.
This is the number 1, this is where most of the real fine fine stuff ended up, you can
see it's pretty much pure iron, this is the number 2 and this is where some of the larger
pieces ended up, you can see pieces up to maybe the head of a pin or a little bit bigger,
but again there is a lot of steel in this as well or Iron and it may not look like it
but these 2 buckets are really heavy, there is a lot of weight there.
This is our number 3 and it was kind of hard to tell on the table where to cut the line
with the splitter um but I did my best and we cut it right between what looked like fresh
iron, kind of a more silvery grey and the silica I think was a lot dirtier, kind of
brown or black and I took a little bit of silica with the iron in the number 3 just
so we didn't lose very much iron but you can see here, there's still a significant amount
of metal in there, but I think some of this finer material and this darker stuff may be
some silicite, like I say I took it with the number 3 just so I could make sure I could
capture all the iron and a little bit of silicate rather then lose any of the iron into the
tailings.
So yeah I think it was a good test, we easily have 50 pounds here, I think we ran somewhere
right around 150-200 pounds of material so we are going to bag this up and send it back
to the customer and he can take a look and see what he thinks.
Thanks for watching and we will see you on the next video.
