According to the material purchasing order, the materials are purchased from suppliers.
Once the materials are available, the production orders are chosen to release to shop floor using some rules.
The fundamental information of the relevant materials in Fig. 1 is shown in Table 1.

Iron-based alloys (steel and cast iron) are currently the main structural materials that provide a high level of mechanical and technological properties along with a relatively low cost.
In order for the NDP to be able to change the properties of the materials into which they are introduced, it is necessary that they be wetted with this material. [6] There are two important models for the wetting efficiency of NDP.
Thus, in order for NDPS to be able to modify the materials into which they are injected, they must be either very small, or must be charged, or their surface must be covered with substances compatible with the material into which they are injected.

The quartz sand dressing plant in the Jiaogan work area of Inner Mongolia have applied H2SO4 as modifier, fatty amine and petroleum sulfonate as collecting agent in the reverse flotation of removing the impurities such as potassium feldspar, generating the final products with SiO2 grade of 97.83% which can be used as raw materials for the production of float glass and high-quality steel cast sand.
After wet screening, material with particle size from 0.147mm to 0.044mm was selected to acid leaching.
