| titleOfInvention | A kind of processing method of mercury ore tailings |
| abstract | The present invention relates to the integrated treatments of mercury ore tailings, more particularly to a kind of processing method of mercury ore tailings, mercury ore tailings is crushed, it is soaked in the auxiliary agent that concentration is 50-60%, and after stirring, standing, when being warming up to 40-60 DEG C, the sodium lignin sulfonate for accounting for the 0.6-0.8 of mercury ore tailings gross mass is added, and after stirring, standing, filtered, obtains filtrate A and filter residue；The proportion that filter residue and sulfonic acid are 1:3-5 in mass ratio is stirred 1.5-2h, adjusting temperature is 50-60 DEG C, and it is > 7 that buffer solution, which is added, and adjusts pH, is filtered, obtains sediment and liquor B；After mixing by filtrate A and liquor B, it is 7 that sulfonic acid, which is added, to pH, and is stirred, after standing, it is filtered, obtains mercuric sulphide, add filtering after sodium chloride solution is stirred, lead chloride and liquid are obtained, this law metallics recovery rate is high, and waste liquid can be recycled, and at low cost, energy time-consuming consumes few. |
