Learn About Silicosis. Silicosis is a lung disease caused by breathing in tiny bits of silica, a mineral that is part of sand, rock, and mineral ores such as quartz. It mostly affects workers exposed to silica dust in occupations such mining, glass manufacturing, and foundry work.
In the most common form of silicosis, called chronic silicosis, these symptoms develop over many years of exposure. However, in the rarer form, called acute silicosis, the symptoms develop very quickly after only a short period of exposure to high levels of silica dust.
