The most important indicator of the mineral industry index is the wollastonite ore ratio, which is the main basis for delineating and evaluating the deposit. The industrial indicators of the currently used wollastonite ore-bearing rate deposits are shown in the table below. Geogrid made from polymer and nano scale carbon black by extrusion technology.It has a property of Roadbed reinforcement, improve stability and bearing capacity. Could prevent roadbed from deformation and crack due to roadbed material wash off. Also could retaining wall bearing capacity improvement. Reinforcement Geogrid,Fiberglass Geogrid,Uniaxial Geogrid,HDPE Geogrid HUATAO GROUP LTD , https://www.huataogroup.com
Other industrial indicators are: thickness that can be collected: ≥1~2m for open mining and ≥1m for pit mining;
The thickness of the stone is removed: the mining is ≥1~2m, and the pit mining is ≥1m;
Stripping ratio: 3
Impurity content: Fe 2 O 3 + TiO 2 ≤ 2%, Cu ≤ 0.3%.
