Silica Precipitation in Acidic Solutions: Mechanism, pH

2009-12-12 · This study is the first to show that silica precipitation under very acidic conditions ([HCl] = 2−8 M) proceeds through two distinct steps. First, the monomeric form of silica is quickly depleted from solution as it polymerizes to form primary particles ∼5 nm in diameter. Second, the primary particles formed then flocculate. A modified Smoluchowski equation that incorporates a geometric

Leaching (metallurgy)

2019-9-30 · Leaching is a process widely used in extractive metallurgy where ore is treated with chemicals to convert the valuable metals within into soluble salts. These can then be washed out and processed to give the pure metal; the material left over is commonly referred to as tailings.Compared to pyrometallurgy leaching is easier to perform, requires less energy and is potentially much less harmful
