Description
новном за счет увеличени выхода чернового концентрата, но при этом резко снижаетс содержание свинца и серебра в черновом концентрате;by increasing the yield of the rough concentrate, but at the same time the lead and silver content in the rough concentrate is sharply reduced;
-дозировка носле ксантогената триэтаноламина практически не снижает извлечени свинца, но за счет снижени выхода чернового концентрата увеличиваетс содержание в нем свинца, а извлечение меди- The dosage of triethanolamine xanthate practically does not reduce lead extraction, but due to a decrease in the yield of the rough concentrate, the lead content in it increases, and the recovery of copper
и серебра снижаетс (в месторождении серебро частично приурочено к медным минералам ). Предполагаетс , что триэтаноламин про вл ет депрессирующее действие на флотируемость медных минералов и пустой породы;and silver decreases (in the deposit, silver is partially confined to copper minerals). Triethanolamine is believed to exhibit a depressant effect on the floatability of copper minerals and waste rock;
-отработанна эмульси , используема самосто тельно - слабый собиратель дл свинцовых минералов даже при больших расходах (600 г/т);- waste emulsion used independently - weak collector for lead minerals, even at high costs (600 g / t);
-дл достил ени максимального эффекта очень важна точка дозировки эмульсии после контакта пульны с ксантогенатом;- to achieve maximum effect, the dosage point of the emulsion after contact is pulped with xanthate;
-отработанна эмульси вл етс более эффективным, чем выше неречисленные , дополнительным реагентом: в посто нных услови х обогаш,ени флотаци интенсифицируетс и заканчиваетс за 20 мин, в результате чего извлечение свинца повышаетс на 2%, серебра - на 4,7% без снижени качества свинцового концентрата.- waste emulsion is more effective than the above non-listed additional reagent: under continuous conditions, the flotation is intensified and ends in 20 minutes, resulting in an increase in lead increase by 2%, silver - by 4.7% without a decrease quality lead concentrate.
Таким образом, основное преимуш,ество данного изобретени состоит в повышении технологических показателей процесса флотации полиметаллических руд, содержаш,их благородные металлы.Thus, the main advantage of this invention is to improve the technological indicators of the process of flotation of polymetallic ores containing their precious metals.
