Dongshan Silica Base, located in Dongshan Island, Fujian Province, is one of the best quality large-scale natural silica sand mines currently developed in China. The original grade is SiO 2 97.2%, Al 2 O 3 1.42%, and Fe 2 O 3 0.15%. The mineral processing process is shown in the figure below. At present, the base handles 353,000 tons of raw sand annually, with an annual output of 300,000 tons of glass sand and 40,000 tons of sand. Glass sand grade; SiO 2 ≥97.5%, Al 2 O 3 ≤1.30%, Fe 2 O 3 ≤0.10%, particle size of 0.5 ~ 0.1mm content of greater than 90%. Molding sand (size 70/140) SiO 2 ≥96.0%, Al 2 O 3 ≤2.0%, Fe 2 O 3 ≤1.00%, CaO+MgO<1.50%, mud content ≤0.30%. MYSAIL series is the result of thinking about the actual needs of commuters. It has new and improved features including, new digital display, digital lock, improved headlight and taillight, and low noise. Yongkang Mysail Technology Co., Ltd. , https://www.mysail-scooter.com
