If venusian clouds contain life, it will be very different than what we know. But terrestrial analogs might still give us ...

A host of problems with existing projects are only making matters worse. Ore quality—the amount of valuable metal in a sample of rock—is declining, forcing miners to dig deeper; mining permits can ...

氧化矿（如氧化铜矿、氧化锌矿）因其特殊的地质成因和化学性质，具有以下核心特征及选矿难点： 强亲水性：氧化矿表面易形成定向排列的水化膜，阻碍捕收剂吸附。例如，硅孔雀石因表面羟基的强极性导致浮选回收率不足50%。 结构复杂性：同一矿床中常 ...

如哈萨克斯坦的康拉德铜矿以0.19%的低品位矿石，吨铜成本控制在1600-1800美元之间。 生物浸出：利用嗜酸菌（如Acidithiobacillus ferrooxidans）进行催化氧化。紫金山铜矿通过优化菌种，铜提取率可达80%，年产阴极铜达2万吨。 技术挑战与解决方案 钙镁干扰：当矿石中 ...

Interactions between microorganisms and metals occur in both natural and anthropogenic environments, encompassing a wide range of processes from microbially catalyzed ...

Introduction: This study aims to enhance the dewatering performance of marine sediment using modified Enteromorpha algae-derived biochar to activate persulfate through an advanced oxidation process.

Study of duodenal bacterial communities by 16S rRNA gene analysis in adults with active celiac disease vs non-celiac disease controls. Virulence-associated genes, antimicrobial resistance and ...
