核心技术Core Technology

生物预氧化技术体系 The Bio-Oxidation Technology System

常温常压下运行的绿色生物冶金体系，同步完成"有价金属释放"与"污染因子控制"。 A green biometallurgy system operating at ambient temperature and pressure — releasing valuable metals while controlling pollutants at the same time.

专有菌群 · 长期驯化Proprietary Consortia · Long Domestication

生物氧化 / 生物淋滤Bio-Oxidation / Bioleaching

特种微生物氧化硫化物、砷化物等矿物包裹层，释放被包裹的有价金属，并使部分重金属进入可控溶液体系。 Specific microbes oxidize sulfide and arsenide mineral layers, liberating encapsulated valuable metals into a controlled solution system.

生物固化 / 稳定化Bio-Stabilization

借助微生物胞外聚合物的吸附、络合、沉淀作用，使溶出金属转化为稳定矿物态，降低迁移性与环境风险。 Microbial extracellular polymers adsorb, complex and precipitate dissolved metals into stable mineral phases, reducing mobility and environmental risk.

闭路循环与无害化Closed-Loop & Detoxification

对浸出液进行收集、净化、分离与循环利用，实现资源回收、废液闭路管理与尾渣无害化处理。 Leachate is collected, purified, separated and recirculated — achieving resource recovery, closed-loop effluent management and harmless residues.

解决方案Solutions

从存量治理到新建矿山的全场景覆盖 Full-Scenario Coverage: Legacy Waste to New Mines

场景 AScenario A

难处理矿与新建矿山开发Refractory Ore & New Mine Development

无需同等级重资产选厂投入，处理规模主要由场地与堆场组织决定，显著降低前期资本开支与扩产门槛。 No heavy-asset concentrator required — throughput is governed by site and heap layout, sharply cutting upfront capex and expansion thresholds.

传统 5000 t/d 浮选厂投资约 5000 万元，生物法资本开支显著更低A conventional 5,000 t/d flotation plant costs ~RMB 50M; biometallurgy needs far less capex
场地充足时，年处理 500 万吨具备较强扩展潜力With ample land, 5 Mt/yr throughput is realistically scalable
高硫、高砷、复杂包裹矿适应性强Highly adaptable to high-S, high-As and complex ores

场景 BScenario B

尾渣与历史固废资源化Tailings & Legacy Waste Valorization

把单纯治理成本转化为"治理 + 资源化"并行模式，回收铜、金、银、镍等有价组分，为历史包袱型固废提供经济闭环。 Transforms pure remediation cost into a parallel "remediation + recovery" model, reclaiming Cu, Au, Ag and Ni from legacy liabilities with an economic closed loop.

调查取样 → 生物淋洗/氧化 → 浸出液回收 → 稳定化 → 复绿Sampling → bioleaching → metal recovery → stabilization → revegetation
削减重金属污染风险，资源化收益反哺治理投入Cuts heavy-metal risk; recovery revenue feeds back into remediation

场景 CScenario C

尾矿库治理与生态修复Tailings Dam Treatment & Restoration

在不大规模外运的前提下实现污染削减与资源回收，形成"治理 + 资源化 + 生态修复"的综合工程。 Reduces pollution and recovers resources without mass off-site hauling — an integrated remediation, valorization and ecological-restoration program.

分区分期施工，可与在线监测、稳定化处理协同设计Zoned, phased construction with online monitoring and stabilization
资源化收益支撑长期治理投入与项目闭环Recovery revenue underwrites long-term stewardship

价值重构Value Reconstructed

生物法不是简单"降成本"，而是重构收益结构——把处理铜、镍、砷、硫的成本环节，转化为释放金属价值的利润环节。 Biometallurgy does more than "cut costs" — it restructures the revenue model, turning the cost of handling Cu, Ni, As and S into profit from released metal value.

以治促收、以收养治。对低品位多金属难选矿、尾渣、尾矿库这类"存量资源"尤为关键——金、银、铜、镍协同回收，砷、硫安全处置，项目抗风险能力更强，更易形成可持续放大的商业模式。 Remediation feeds recovery, and recovery funds remediation. For low-grade polymetallic ores, tailings and dams — "stock resources" — co-recovery of Au, Ag, Cu and Ni with safe As/S disposal delivers stronger resilience and a scalable business model.

项目案例Case Study

秘鲁铜渣生物浸出：3 天浸出率 62.3% Peru Copper Slag Bioleaching: 62.3% in 3 Days

对秘鲁合作方热炼洞渣开展生物搅拌浸出小试，第三方化验证实铜由 0.91% 降至 0.49%（干样）。现场堆浸约需 4 个月完成；下一步拟开展约 1 万吨中试，验证后即刻转入规模化处理。 A bench-scale agitated bioleaching test on the Peruvian partner's smelted slag showed copper falling from 0.91% to 0.49% (dry basis, third-party assays). Field heap leaching is estimated at ~4 months; a ~10,000 t pilot is the next step before full-scale processing.
