Abstract |
A small foundry tested the replacement of moulding sand by olivine, a magnesium iron silicate containing almost no free silica, in certain operations. Comparative chemical and physical characteristics are indicated, and foundry activities are described. Air quality was monitored by personal sampler, cascade impactor, and tape sampler. The concentration of free silica was reduced to acceptable levels, but contamination from processes using silica must be guarded against. |
