Sure, but where’s the answer? Why isn’t anyone responding? It’s frustrating
This issue is somewhat outside the scope of the chemical industry, so not many members are familiar with it. We can only wait and see.
First, let’s correct the original poster’s question: it should be about the amount of silica contained, rather than free silica. Furthermore, most ores contain silica, and the exact amount requires measurement; for example, quartz can contain up to 99% silica, but there are also varieties with lower levels.
Hasn’t anyone answered yet? You asked too many questions at once and scared everyone away.
