This paper examines the critical research works that have been conducted on laboratory or pilot scales to extract gold from ores using the lixiviants that are produced by microorganisms. Different flowcharts are included to clearly show the central points of the selected published works and the key results to those in the mining and metallurgy industries who are pursuing new alternatives to cyanide in the gold leaching process. Finally, based on the lessons learned, five different flowcharts are developed to identify possible direct gold dissolution scenarios from refractory and non-refractory ores using iodide oxidizing, cyanogenic, and amino acid-excreting bacteria.

本文考察了在实验室或中试规模上进行的关键研究工作，以使用微生物产生的浸出剂从矿石中提取黄金。包括不同的流程图，以向在金浸出过程中寻求氰化物的新替代品的采矿和冶金行业的人员清楚地显示所选已发表作品的中心点和主要结果。最后，根据吸取的经验教训，开发了五种不同的流程图，以确定使用碘化物氧化细菌、氰基细菌和氨基酸分泌细菌从难熔和非难熔矿石中可能直接溶解金的场景。
