| titleOfInvention | A kind of preparation method of mispickel inhibitor |
| abstract | A kind of preparation method of mispickel inhibitor, includes the following steps：(1) 20~25g ortho-xylene is added to 150~200ml volumetric concentration is in 15~20% sulfuric acid solutions, heating is cooled to 10~15 DEG C after making it dissolve, and being slowly added to 20~30ml mass percentage concentration at this temperature is that 10% sodium sulfide solution obtains product 1；(2) 20~25g nigrosine and 100~150ml 1mol/L sodium hydroxide are configured to solution and are cooled to 10~15 DEG C, be coupled under the conditions of pH10.5~11 with product 1 and obtain product 2, product 2 and acid black be coupled under the conditions of pH10~11 black powder soluble easily in water is the mispickel inhibitor.The mispickel inhibitor being prepared into is able to suppress mispickel, does not generate inhibiting effect to pyrite, is easily isolated sulfoarsenic mineral, obtains sulphur, arsenic concentrate. |
