Извлечение золота из горных пород | Выщелачивание золотой руды

Hello, refining enthusiasts! In this video, I process 93 kg of gold ore to test its actual gold content, starting with an XRF assay estimate of 40 grams per ton. Follow along as I go through grinding, pH adjustment, cyanide leaching, filtration, and gold precipitation using ferrous chloride. Despite careful processing, we managed to recover only 1 gram of gold—far less than expected! Watch the full process, learn from the challenges, and share your thoughts in the comments.

Always use proper protective gear and follow strict safety protocols when handling chemicals. Cyanide Titration Using KI & 0.01M AgNO₃ This method determines free cyanide concentration by titrating with silver nitrate (AgNO₃) using potassium iodide (KI) as an indicator. Procedure: Prepare Sample – Take a known volume of the cyanide solution. Add KI – Acts as an indicator; forms yellow AgI at the endpoint. Titrate with 0.01M AgNO₃ – Until permanent yellow turbidity appears. Calculate Cyanide (mg/L): 1000 × AgNO₃ Volume (mL) / Sample Volume (mL) This method provides a quick and accurate cyanide concentration measurement.
