The cyanide removal step is not emp

The cyanide removal step is not employed to produce an effluent of suitable quality to meet the imposed effluent discharge limits but rather relies on fur- ther removal of cyanide by natural degradation in the tailings ponds. The regulated parameters in the effluent from the tailings pond are usually below the objective limits of this process.
Recently, brand name products such as DTOX have been introduced, based on the sulphide precipitation process principles (Min- eral Process Control, 2013). The reaction between cyanide and polysulfide–sulfur contained in DTOX converts hydrogen cyanide to thiocyanate. In addition, heavy metal ions can be precipitated as cyanide, and free and complex cyanides are neutralised. The end products released to the environment contain carbonates and ammonia. It is claimed that the reaction is safer and the rates are more rapid than those of hypochlorite. The experiments conducted to investigate the reaction in a 2% (20,000 mg/L) solution
of sodium cyanide revealed that the reaction was 95% complete

Các bước loại bỏ xyanua không được sử dụng để sản xuất một ef fl uent chất lượng phù hợp để đáp ứng giới hạn thải ef fl uent áp đặt mà là dựa trên loại bỏ ther Hơn nữa cyanide do sự thoái hóa tự nhiên trong ao chất thải. Các thông số quy định trong ef fl uent từ chất thải ao thường dưới mức mục tiêu của quá trình này.
Gần đây, các sản phẩm thương hiệu như DTOX đã được giới thiệu, dựa trên các nguyên tắc quá trình kết tủa sunfua (Min- Process Eral Control, 2013). Phản ứng giữa xianua và polysul fi de-lưu huỳnh chứa trong DTOX chuyển hóa hydro xyanua để thiocyanate. Ngoài ra, các ion kim loại nặng có thể được kết tủa như xyanua, và xianua tự do và phức tạp được vô hiệu hóa. Các sản phẩm cuối cùng phát hành cho môi trường chứa cacbonat và amoniac. Đó là tuyên bố rằng phản ứng là an toàn hơn và giá đều là nhanh chóng hơn so với những người hypochlorite. Các thí nghiệm được tiến hành điều tra các phản ứng trong 2% (20.000 mg / L), giải pháp
của natri xyanua tiết lộ rằng phản ứng là 95% hoàn thành
