Description
Так при аналогичных услови х осуществлени процесса по предложенному способу при сгущении кимберлитовой глины содержание твердого в сгущенном продукте повышают с 35 до 48%, значительно повышаетс скорость осаждени твердой фазы, а объем осадка уменьшаетс с 115 см до 75 см с одновременным расходом коагул нта в 2 раза.So, under similar conditions of the process according to the proposed method, when kimberlite clay is thickened, the solid content in the condensed product is increased from 35 to 48%, the solid phase deposition rate significantly increases, and the sediment volume decreases from 115 cm to 75 cm with simultaneous consumption of coagulum in 2 times.
Пример 1. Суспензию кимберлитовой глины, содержащей 9,5% твердого продукта , раздел ют на два потока в соотнощении 1:1. Часть потока обрабатывают катионным полимером, в частности полиакриламидом (ПАА) в количестве 50 г/т, другую часть анионным полимером - ВА-2 в количестве 50 г/т. Обработанные части соедин ют и направл ют на сгущение в отстойНИКИ .Example 1. A suspension of kimberlite clay containing 9.5% of solid product is divided into two streams in a 1: 1 ratio. Part of the stream is treated with a cationic polymer, in particular polyacrylamide (PAA) in an amount of 50 g / t, the other part with an anionic polymer — BA-2 in an amount of 50 g / t. The treated portions are joined and directed to thickening in a settling tank.
Пример 2. Суспензию медного концентрата с содержанием твердого продукта 18% раздел ют на два потока в соотношении 1 : 1,5, одну часть потока обрабатывают ПАА в количестве 40 г/т, а другую ВА-2 в количестве 60 г/т. Обработанные части соедин ют и направл ют на сгущение в отстойники .Example 2. A suspension of copper concentrate with a solid content of 18% is divided into two streams in a ratio of 1: 1.5, one part of the stream is treated with PAA in an amount of 40 g / t, and the other one is BA-2 in an amount of 60 g / t. The treated portions are joined and sent to a thickener for settling tanks.
Степень обезвоживани в примерах 1 и 2 определ ют по показателю объема получаемого осадка, а врем процесса - по показателю содержани твердого продукта в обработанной суспензии.The degree of dewatering in examples 1 and 2 is determined by the volume of the resulting precipitate, and the process time is measured by the solid content of the treated suspension.
В результате объем осадка уменьшают в 1,5-2 раза по сравнению с известным способом в равных услови х обработки. Содержание твердого продукта в суспензии повышаетс до 48% по сравнению с 35% по известному , а расход флокул нта уменьшаетс в 2 раза.As a result, the volume of sediment is reduced 1.5-2 times as compared with the known method under equal treatment conditions. The solids content in the suspension is increased to 48% as compared to 35% of the known, and the consumption of flocculant is reduced by 2 times.
Предложенный способ позвол ет снизить расход дорогосто щих флокул нтов и получить высокие технологические показатели сгущени .The proposed method allows to reduce the consumption of expensive flocculants and to obtain high technological indicators of condensation.
