The ground ore can be sent directly to extract gold or beneficiated; pemisahan flotasi <\/strong>dan pemisahan gravitasi<\/strong> are the most used methods. The obtained concentrate and the tailings are disposed of separately.<\/p>\n For refractory ores, pretreatment is required. In order to release gold from sulfide ore bodies, such as pyrite and arsenopyrite, oxidative pretreatment (such as burning, pressure oxidation, or bio-oxidation) is generally employed. The refractory ore can be enriched by flotation before oxidation. The oxidation process produces by-products that must be specially processed before the next step.<\/p>\n Metode klasik untuk mengekstraksi emas adalah pertama-tama melarutkannya dengan larutan sianida, kemudian mengganti emas dengan logam dari larutan yang mengandung emas, atau menyerapnya dengan metode bubur karbon, dan kemudian mengambil emas dari karbon. Sisa sianida harus dihilangkan sebelum mengembalikan atau membuang cairan rendaman ke lingkungan.<\/p>\n To recover gold from the cyanide solution, the gold can be adsorbed on the activated carbon during the extraction process (CIL) or after the extraction (CIP) or replaced with metal zinc in the displacement precipitation system. There are many options for tailings disposal, such as sealing ponds, decanting ponds, discharging into beaches and lakes, ground deposit, marine disposal, backfilling, dry landfills, etc. This is related to the choice of the best disposal method and the site holding point, and also depends on the distance from the residential area, terrain, hydrology, local regulations, tailings characteristics, and real estate management policies.<\/p>\n Pengangkutan dan penyimpanan reagen merupakan pertimbangan penting dalam studi apa pun dan harus ditangani selama fase desain proses metalurgi. Pengangkutan dan penyimpanan reagen, serta rencana kontinjensi, harus dipertimbangkan secara rinci.<\/p>\n <\/p>\n All of the processing operations mentioned above have a potential impact on the environment and must be considered during the working flow design phase. For example, noise, dust, smoke, chemical reagents, liquid, solid waste, and so on.<\/p>\n <\/p>\n Each processing stage poses unique environmental risks:<\/p>\n 1. Menghancurkan dan menggiling<\/strong> 2. Gold ore dressing<\/strong> 3. Pretreatment<\/strong> 4. Extraction of gold<\/strong> <\/p>\n Effective gold extraction balances metallurgical efficiency with environmental stewardship. From ore comminution to tailings disposal, proactive mitigation\u2014such as reagent optimization, waste containment, and emissions control\u2014is essential for sustainable operations.<\/p>\n Partner with Experts<\/strong>: JXSC, with 40+ years of experience in gold processing, offers tailored solutions for sulfide and alluvial ores, ensuring compliance and efficiency.

Environment Considerations<\/h2>\n
\nThe crushing and grinding process of the ore produces noise and dust<\/strong>, which mainly affects the environment of the workplace. Sometimes, a reagent<\/strong> such as cyanide is added to the grinding circuit to promote the dissolution of gold, and the added reagent also has an effect on the working environment.<\/strong><\/p>\n
\nIn the flotation process, the potential source of environmental impact is mainly chemical reagents<\/strong>, which may affect the field and the surrounding environment. The flotation tailings are related to some of the following issues<\/strong>
\n(1) Air buangan yang bersifat asam
\n(2) Kebocoran logam yang dapat larut dan kehilangan permukaan
\n(3) Kekeruhan air drainase<\/p>\n
\nPretreatment of gold ore and concentrate, usually using oxidation<\/strong> to decompose gold-bearing sulfide minerals such as pirit<\/a> and arsenopyrite. The oxidation products are treated to comply with environmental protection-related waste disposal regulations. In the case of calcination, the sulfur dioxide and arsenic-containing gases<\/strong> produced by it cannot be directly discharged into the atmosphere.
\nProduk oksidasi ini dapat dihilangkan dengan flotasi, dan tailing emas atau produk oksidasi perlu diangkut ke lokasi terpencil untuk pembuangan khusus.<\/p>\n
\nA common method of gold extraction is to dissolve the gold ore in an alkaline solution of cyanide. In any case, for the environmental protection of the workplace, the storage and disposal of the reagents<\/strong> should be seriously considered. The waste slag after gold extraction can be disposed of together with flotation tailings. These solids may contain some residual leaching agents.
