Silica Info

Posted in: , on 10. Oct. 2008 - 02:04

I have a connection to a possible silica deposit.

I'm looking to get the sand tested to see what grade or quality the sand is.

1. What kind of testing am I looking to get done? Percent of silica content or are there other possible qualities it could have? Size, etc..

2. What lab does this kind of testing? I'm in Calgary, Canada. Do I have to ship a sample to get this done?

3. Once I have a grade analysis how can I then get an approximate market value for that grade to see if it's economical to mine? Is there a common benchmark for silica content to be economical or not (eg, anything less than 90% silica is worthless)

Thanks in advance for any help

Don't you have several university geology departments in the neighborhood that do assay work? that would be your first step and the easiest and then you will know what you have on your hands.

Its simply a matter of assay testing for silica content, purity of sample, waste content and then going from there to determine the size of the deposit and then looking for potential buyers of the silica sand.

A couple of years a ago there was huge depost of silica sand in texas for sale and it had rail access for loading cars rioght from the deposit and the silica content was listed etc-dont remember it all the deposit was large or that depends on your vision of a deposit of any in situ ore. Market conditions and the current price for the ores are another thing as it all depends on where the market is and how big the market is and the current state of the market and whether anyone is in the market for more silica.

I will add more when I get a minute.

White silica sand

pure silica sand

fused silica sand

sample silica sand grade percentages listed below

99.72 %

Intertek Assay Services:

They have an assay lab in Calgary

The contact phone number for north america is:

1-888-400-0084 and they can get you their number but if they are in the phone book in Calgary you can call direct I am sure.

Just remember "one sample does not an assay make".

Just take care in how hard you reach for the brass ring on the merry go round due to potential mineral assays and the other thing is the deposit size as simple economics is the 900 lb. gorrilla in the closet that will rule any decision by a potential buyer.

Nor am I going to lessen the paper trail risk in mineral stake claims with your goverments current policy on mineral claims versus land ownership rights.

As someone may already own the silica mineral rights ;^0-

The article about the mineral rights in the "Province of Ontario" a few weeks ago in the New York Times was an eye opener for sure.

Based on my experience, the assaying of the silica depends on the used of the type of the silica.

Silica is widely used material and the used depends on its type, its composition , grade and the grain size. The most needed type of silica is the quartz sand and the fused quarts.

In electronics industry, silica needed is 99.9999% SiO2 content in powder. In glass, for amber must be 96% SiO2 content up with iron oxide not more than 0.010%. And for flint glass, SiO2 content must be more than 97%or 98% with iron oxide not more than 0.040%.If SiO2 is at range of 85% to 95%, that material can be used in adhesive industry like cement manufacturing. If SiO2 content is above 93% and chloride is less than 0.010% and flourine is less than 0.0015%, that material can be used in copper smelting.

Silica fused quartz is very useful in ferro silicon and in copper smelting also.Can also be used in cement board industry.

Another inportant consideration of silica is also the grain size, different manufacturing plant has its own limit of sizes. Just like in glass, grain size must be from 140 mesh to 20 mesh, rejects sizes are below 140 and above 20 mesh. In copper smelting, the size mostly acceptable is passing 20 mesh size. And silica fused quarts used in feroo silicon must be 3 to 4 inches in size. Silica fused quartz for copper smelting must be 1.5 inches to 3 inches in size. Silica fused quartz for cement board, size must be below 1 inch.

Anyway, just assay the important composition of the silica raw material first including the sizes. Imform me once you have it already so i can help you determine in what industry that silica can be used.

As what i said, silica is a widely used material. Not just used on what i mentioned above.Toothpaste abrasives,dishwashing paste, construction industry, ceramics , steel flux and so with others.

I know much information of silica because i supplied silica sand before to glass, cement and dishwashing paste industry.We just encountered problem at the time that another silica mine was opened with a distance much shorter than our source.

Hi

There is a British Standard for glassmaking sands. For testing, you need to contact Glass Technology Services, email: info@glass-ts.co.uk - GTS are based in the UK and offer this kind of service.

i have access to a silica sand deposit with a rough estimate 70,000 tons reserves.

sand chemical analysis is sio2 98.4% and Fe2o3 .oo7%.

what is the cheapest method of 2 cleaning the sand of the fe2o3.

cheers for the help..

p.s do you know of any value added markert which this material as is would suit.
