INTRODUCTION. Silicon (Si) in a chemically combined form is ubiquitous in nature. The Si content of soils can vary dramatically from <1 to 45 % dry weight (Sommer et al., 2006), and its presence in the form of silicic acid [Si(OH) 4] (or its ionized form, Si(OH) 3 O −, which predominates at pH > 9) allows its uptake by plants.Silicic acid is …

The plants beneficiate a low-grade ore that was historically considered waste material. This is achieved by removing silica and alumina from the feed material, as well as gravity separating low-grade from high-grade ore. Silica levels, which range from 14% to 20%, have reduced to 6.4% after processing.
