以陕西某含碳微细粒金矿石为研究对象，其金品位为 5.55 g/t，自然金被大量碳质、硅质等矿物包裹，无法高效富集。针对该矿石矿物结构复杂导致的金元素提取困难现状，为实现深度脱碳提金的目的，采用“固化成型焙烧—氰化浸出”提金工艺，研究矿石在逐步氧化过程中金元素的富集状态。研究结果表明：将粒度为-2 mm的原矿在 15 MPa压力下固化压制成型砖，成型砖在550 ℃下焙烧 16 h，碳脱除率达到 87.06 %；在磨矿细度-0.074 mm 占比 75 %，某环保提金剂用量2 000 g/t，矿浆浓度40 %，矿浆pH值大于11，常温氰化24 h条件下，金浸出率最高达91.68 %。研究结果为含碳微细粒金矿石工业化利用提供了技术指导。  

 This study focuses on a carbonaceous fine-grained gold ore from Shaanxi Province, with a gold grade of 5.55 g/t, where native gold is extensively encapsulated by carbonaceous and siliceous minerals, hindering efficient   enrichment. To address the challenges in gold extraction caused by the complex mineral structure and achieve deep carbon removal and gold recovery, а "curing roasting-cyanidation leaching"process was employed to investigate gold enrichment during progressive oxidation. Key findings include: raw ore (particle size of -2 mm) cures into bricks under 15 MPa pressure; roasting the bricks at 550 °C for 16 h achieved a carbon removal rate of 87.06 %:; under optimized conditions (grinding fineness of -0.074 mm accounting for 75 %, eco-friendly gold leaching agent dosage of 2 000 g/t. pulp density of 40 %, pH > 11, and 24 h cyanidation at room temperature), the maximum gold leaching rate reached 91.68 %. This research provides technical guidance for the industrial utilization of carbonaceous fine-grained gold ores.
