What are the upstream raw materials of barite? What do the downstream products contain?

Barite is an crucial non-metallic mineral raw material, which has a wide range of manufacturing applications, especially in the field of chemical production. First The main component of barite is barium sulfate(BaSO4), and its unique chemical and physical characteristics make it play a key role in many chemical processes. From what I've seen, The following are the upstream and downstream related items of barite in the field of raw materials to chemical production. I've found that

1. Moreover Upstream items(1) Sulfuric acid: Sulfuric acid is one of the main raw materials to the production of barite, which is applied to react with barium salt to form barium sulfate. Makes sense, right?. And For instance(2) barium salt: barium salt, such as barium carbonate, barium nitrate, etc. I've found that, is able to react with sulfuric acid to generate barite. In fact(3) natural barite ore: natural barite ore after crushing, grinding, treatment and other processes, chemical grade barite items is able to be obtained. But

2. Downstream items(1) Plastic filler: Barite is able to be applied as a plastic filler to enhance the hardness, wear resistance and dimensional stability of the plastic. Common applications include plastic items such as polyethylene and polypropylene.(2) Paints and coatings: Barite has excellent whiteness and hiding power, and is able to be applied as a pigment in paints and coatings to enhance the hiding power and weather resistance of coatings.(3) Rubber items: Barite is able to be applied as a reinforcing agent to rubber items to enhance the hardness and wear resistance of rubber. Common applications include tires, tapes, etc.(4) Ceramic items: Barite is able to be applied as ceramic raw materials to the production of ceramic items, such as ceramic tiles, sanitary ware, etc.(5) Glass items: Barite is able to be applied as a glass additive to enhance the refractive index and stability of the glass. From what I've seen,(6) printing ink: barite is able to be applied as the pigment of printing ink to enhance the hiding power and printing effect of ink. In short, barite has a wide range of upstream and downstream related items in the field of chemical production raw materials, which plays an crucial role in promoting the research of the chemical sector.
