合肥万泉非金属矿科技有限公司成立于2011年10月，公司主要经营范围：非金属矿选矿实验分析，选矿工程设计、安装，选矿技术转让、咨询，高纯石英砂、硅微粉及尾矿技术开发和应用等。前身是广宝来特种石英（凤阳）科技有限公司，广宝来特种石英（凤阳）科技有限公司是一家为太阳能光伏电池超白玻璃厂提供高纯低铁石英砂的专业生产厂家。广宝来主要产品：低铁石英砂: SiO2≥99.5%±0.2%, Fe2O3≤0.005%± 0.001%
技术优势：光伏发电离不开超白玻璃，超白玻璃要求其成分中Fe2O3≤0.009%，具有高透光率，透光率决定玻璃的品质，浮法玻璃的透光率为86%，而超白玻璃透光率可达92%以上，太阳能光伏发电系统的玻璃基片就需要使用超白玻璃。超白玻璃的生产对使用量主要原料石英砂要求特别严格，SiO2≥99.6% ，Fe2O3≤0.0050%±0.0010%，否则无法保障超白玻璃其成分中Fe2O3≤0.009%。随着光伏发电的发展，超白玻璃的需求量成数倍增长，高纯度低铁石英砂用量也随之增长。用酸洗石英砂，但酸洗产量低，成本高，污染难解决，远远不能满足光伏产业的需求。公司拥有自主知识产权的浮选工艺和捕收剂(发明专利号：200910116471.8， 200910144544.4，201510779912.8),把普通Fe2O3≤0.012%石英砂制成Fe2O3≤0.0050%±0.0010%的高纯低铁石英砂。
2010年度安徽省战略性新兴产业科技攻关计划项目中，安徽省科学技术厅针对凤阳县石英尾砂固体废弃物所造成严重的环境污染问题，提出企业开发出废弃尾砂中的石英资源的综合利用技术，广宝来公司承担“凤阳超白玻璃石英砂尾矿综合利用关键技术研究”项目计划。
企业有一个研发团队，并与相关大学进行产学研合作。公司2006年开始研究成功采用反浮选工艺，阴阳离子捕收剂，把普通石英砂制成高纯低铁石英砂。之后又采用浮选工艺结合煅烧、水淬、酸洗、高纯水清洗、无污染粉碎、强磁选等一系列工艺，把SiO2≥99.8%的石英矿石制成SiO2≥99.99%高纯石英砂，用于单晶硅、多晶硅生产用石英坩埚原料及石英玻璃、光学玻璃、水晶玻璃、光热玻璃原料等。
对于尾矿综合利用，万泉公司通过技术创新和技术攻关，公司拥有自主知识产权的浮选工艺和捕收剂(发明专利号：201310071037.9，201310070979.5，201410485021.7)，成功从钼、金、铜矿等有色金属尾矿中分选石英、长石制造平板玻璃、器皿玻璃、微晶玻璃、泡沫玻璃、陶瓷等产品，工艺技术成熟。从尾矿中把石英、长石分出来后，剩下的尾矿就是富矿，再分选出其中的有色金属，对每个有价组分充分回收，充分利用，经济价值十分巨大，其附加值甚至会超过主业，实现了尾矿综合利用真正意义上的“吃干榨尽”。
开展尾矿资源综合利用和减排，利用尾矿资源，少开矿山，少占土地，走循环经济之路，资源节约，环境友好，使之变废为宝、化害为利。
英文翻译：Hefei Wanquan non metallic mineral Technology Co., Ltd. was established in October 2011. Its main business scope includes: experimental analysis of non-metallic mineral processing, design and installation of mineral processing engineering, transfer and consultation of mineral processing technology, development and application of high-purity quartz sand, silica powder and tailings technology, etc. Formerly known as guangbaolai special quartz (Fengyang) Technology Co., Ltd., guangbaolai special quartz (Fengyang) Technology Co., Ltd. is a professional manufacturer of high-purity low iron quartz sand for solar photovoltaic cell ultra white glass factory. Main products: low iron quartz sand: SiO2 ≥ 99.5% ± 0.2%, Fe2O3 ≤ 0.005% ± 0.001% technical advantages: photovoltaic power generation cannot be separated from ultra white glass, which requires Fe2O3 ≤ 0.009% in its composition, with high transmittance, which determines the quality of glass. The transmittance of float glass is 86%, while the transmittance of ultra white glass can reach more than 92%. The glass substrate of solar photovoltaic power generation system needs to use ultra white glass. The production of ultra white glass requires very strict use of quartz sand as the main raw material, SiO2 ≥ 99.6%, Fe2O3 ≤ 0.0050% ± 0.0010%, otherwise, Fe2O3 ≤ 0.009% in the composition of ultra white glass cannot be guaranteed. With the development of photovoltaic power generation, the demand for ultra white glass has multiplied, and the demand for high-purity low iron quartz sand has also increased. Using acid pickling quartz sand, but the output of acid pickling is low, the cost is high, and the pollution is difficult to solve, which is far from meeting the needs of photovoltaic industry. The company has its own intellectual property flotation process and collector (invention patent No.: 200910116471.8200910144544.4201510779912.8). Ordinary Fe2O3 ≤ 0.012% quartz sand is made into Fe2O3 ≤ 0.0050% ± 0.0010% high-purity low iron quartz sand. In 2010 Anhui strategic emerging industry science and technology research plan project, Anhui Science and Technology Department put forward the comprehensive utilization technology of quartz resources in the waste tailing in view of the serious environmental pollution caused by the solid waste of quartz tailing in Fengyang County, and guangbaolai company undertook the project of "Research on key technology of comprehensive utilization of Fengyang ultra white glass quartz tailing" Plan. The company has a R & D team and cooperates with relevant universities in production, teaching and research. Since 2006, the company has successfully adopted reverse flotation process and anion and anion collector to make ordinary quartz sand into high-purity low iron quartz sand. After that, a series of processes, such as calcination, water quenching, acid pickling, high-purity water cleaning, pollution-free grinding and strong magnetic separation, were used to make silica ore with SiO2 ≥ 99.8% into high-purity quartz sand with SiO2 ≥ 99.99%, which is used for raw materials of quartz crucible, quartz glass, optical glass, crystal glass and photothermal glass for monocrystalline silicon and polycrystalline silicon production. For the comprehensive utilization of tailings, Wanquan company, through technological innovation and technological tackling, the company has independent intellectual property rights flotation technology and collector (patent number: 201310071037.9201310070979.5201410485021.7), successfully selected quartz and feldspar from molybdenum, gold, copper and other non-ferrous metal tailings to make flat glass, glass, glass, foam glass and ceramics. And other products with mature technology. After the quartz and feldspar are separated from the tailings, the remaining tailings are rich ores, and then the non-ferrous metals are selected. The valuable components are fully recovered and fully utilized. The economic value is very huge, and the added value even exceeds the main business, realizing the true meaning of "eating, drying and squeezing out" in the comprehensive utilization of tailings. Carry out the comprehensive utilization and emission reduction of tailings resources, make use of tailings resources, open less mines, occupy less land, take the road of circular economy, save resources and make environment friendly, so as to turn waste into treasure and turn harm into profit.
