In this approach, the well-mixed raw material of tungsten concentrate and calcium carbonate is roasted at 800–850 °C to convert tungsten minerals to Ca 3 WO 6 (Li et al., 2015) and/or Ca 3−x (Fe, Mn) x WO 6 (0 < x ≤ 1) (Li et al., 2016); Subsequently, the roasted product is leached in ammonium carbonate solution at 30–80 °C to obtain ...

The tungsten filter had a more pronounced beam hardening effect at the beam edge than along the central ray. For example, the dose rate in air at the beam edge for a 30 x 30 cm2 field was 13% higher than along the central ray without the tungsten filter. The addition of the 1/8 in. filter decreased this horn to 6%.
