Abstract
A floatation separation method of micro-fine-particle cassiterite minerals and quartz includes: using sodium carbonate as pH value adjusting agent, using sodium silicate and direct green and larch extract as the inhibitor of quartz and fine silt minerals, using salicylaldoxime as the activating agent of the micro-fine-particle cassiterite minerals, and using BY-9 as the collecting agent of the micro-fine-particle cassiterite minerals. By the method, floatation separation of the micro-fine-particle cassiterite minerals and the quartz is simple in flow and low in agent use amount, and the micro-fine-particle cassiterite minerals can be recycled effectively; under the condition that the antimony content of the supplied minerals is 0.36-0.60, tin concentrate with the tin content of 11.35-17.27% and the recycling rate of 71.33-75.78% is acquired after floatation separation.
Description
One, technical field
The present invention relates to a kind of floatation separating method for mineral, particularly a kind of micro fine particle mineral and quartzy flotation separation method.
Two, background technology
The ore dressing of micro fine particle mineral, is still one of difficult problem in the outer ore dressing field of Now Domestic, since the sixties in last century, has carried out large quantity research both at home and abroad, but all do not made a breakthrough.Micro fine particle ore dressing both at home and abroad at present is mainly reclaimed micro fine particle by methods such as gravity treatment, weight-floating process integrations; But containing a large amount of quartz and thin mud in, gangue mineral low for cassiterite fine size, grade, still good recovery method is not found at present, the annual fine fraction cassiterite run off in mine tailing is worth tens billion of, if adopt method for floating micro fine particle to be separated with quartz or other impure mineral, this has important practical significance to the recovery of cassiterite resource.
Three, summary of the invention
The object of the present invention is to provide a kind of cassiterite mineral and quartzy flotation separation method, it can reclaim micro fine particle mineral, obtains higher grade and the rate of recovery.
The present invention achieves the above object by the following technical solutions: a kind of micro fine particle mineral with quartz flotation separation method, concrete steps and regime of agent as follows:
(1) slurry pH is adjusted to be 8 ~ 9 with sodium carbonate,

(3) activator of micro fine particle mineral is made with salicylaldoxime,
(4) collecting agent of micro fine particle mineral is made with BY-9,
(5) in floatation process, after ore pulp being crossed 100 mesh sieves, first adjusting slurry pH with sodium carbonate is 8 ~ 9, then add waterglass and direct green and larch extract and suppress quartz and thin mud mineral, add salicylaldoxime activated fine grain cassiterite mineral again, finally add BY-9 to carry out collecting to micro fine particle mineral and obtain cassiterite concentrate
(6) the total consumption of medicament is:
During use, described medicament is first mixed with following concentration expressed in percentage by weight:
Unless otherwise indicated, percentage of the present invention is mass percent, and each constituent content percentage sum is 100%.
Described BY-9 is a kind of collectors for cassiterite that Beijing Non-Ferrous Metal Research General Academy produces, on sale.
Outstanding advantages of the present invention is:
1, can make micro fine particle mineral and quartz mineral FLOTATION SEPARATION, obtain Theil indices 11.35 ~ 17.24%, the rate of recovery is the Tin concentrate of 71.33% ~ 75.78%.
2, flowage structure is simple, and dosing is few.
