The invention discloses a fluorite pellet which comprises the following raw materials in parts by weight: 50-150 parts of wet fluorite powder and 1-30 parts of a pellet binder, and relates to the technical field of fluorite pellets. According to the fluorite pellet and the production method thereof, laterite is used as a pellet binder to replace part of bentonite and reduce the doping amount of the bentonite, the defects that in a traditional process, bentonite is completely used as the binder, the residual quantity is large, and the TFe grade of the pellet is reduced are overcome, starch is added into a material, can be rapidly dissolved and wraps the surface of material particles, and the content of the bentonite is reduced. Compared with a conventional corn gelatinized starch bonded pellet, the corn gelatinized starch bonded pellet has better viscoelasticity, the drop strength of a wet pellet is improved, and after drying, a solid phase bonding bridge can be formed to bond material particles, so that the pellet has excellent compressive strength; the low-viscosity water-soluble phenolic resin is adopted and can form a net-shaped structure with the materials, so that the pellets have excellent heat resistance.
本发明公开了一种萤石球团，其原料按重量份比包括：湿萤石粉50‑150份和球团粘结剂1‑30份，本发明涉及萤石球团技术领域。该萤石球团及其生产方法，通过红土矿作为球团粘结剂，代替部分膨润土，降低膨润土掺量，克服了传统工艺完全采用膨润士作为粘结剂，残留量大，降低球团矿TFe品位的缺陷，淀粉加入到物料中，可迅速溶解，并包裹在物料颗粒表面，形成一层具有粘结作用的薄膜，同时填充颗粒间的缝隙，促使球团初期成型，相较于常规玉米糊化淀粉粘结的球团具有更好的粘弹性，提高湿球的落下强度，烘干后，可形成固相粘结桥粘结物料颗粒，使球团具有优异的抗压强度，采用低粘度水溶性酚醛树脂，可与物料形成网状结构，使球团具有优良的耐热性能。
