Description
A Preparation Method of Lead-zinc-Sulphur Mixing, Floating and
Separating Inhibitor
The invention relates to a preparation method for a beneficiation reagent,
in particular to a preparation method for a sphalerite and pyrite inhibitor.
The flotation process of lead-zinc ores can be divided into a preferential
flotation process and a mixed flotation process. For ores which are high in lead
content and are difficult to suppress zinc-sulfur ores, the process of firstly
floating lead and then floating zinc is generally adopted; the preferential
flotation process of lead-zinc ores is generally preceded by adding an inhibitor,
followed by a collector, which is beneficial to adsorbing the inhibitor onto the
sphalerite and pyrite surface, and is relatively weak on the effect of the
sphalerite and pyrite surface by preferentially floating collectors such as black
powder with strong selectivity. Therefore, the preferential lead-zinc flotation
separation process generally adopts conventional inhibitors such as zinc
sulfate, limes or sodium sulfite to effectively inhibit sphalerite and pyrite. For
the ores with lower lead-zinc content, the preferential flotation cost is higher,
and a hybrid flotation process is generally adopted for adding copper sulphate
to active sphalerite and pyrite, and adding butyl xanthate with strong collecting
ability to float all sulfide ores; the disadvantage of the mixed flotation process is
that it is difficult to separate the lead and zinc flotation. The general reagents such as zinc sulfate, lime and sodium sulfite are difficult to obtain ideal indexes, and sometimes they cannot be separated at all.
The objective of the invention is to provide a preparation method of a
pyrite and sphalerite inhibitor, which can realize inhibiting pyrite and sphalerite
in a mixed flotation prior to addition of a collector system. The invention
develops a preparation method for effective suppression of sphalerite and
pyrite for the lead-zinc-sulfur mixed flotation system.
To achieve the objective, the invention adopts the following scheme: a
preparation method of a lead-zinc mixing, floating and separating inhibitor,
comprising the following steps:
(1) taking 1 part of Congo red and 0.3 part of sodium hydroxide to prepare
a 30wt.% solution, and stirring the solution for 15 minutes at a temperature of
°C;
(2) taking 3 parts of zinc sulfate, 1 part of sodium hydrosulfite and 0.2 part
of pyrogallic acid to prepare a 30wt.% aqueous solution, and stirring the
aqueous solution for 15 minutes at a temperature of 20-25°C;
and (3) mixing products obtained by the steps (1) and (2), stirring for 10
minutes at a temperature of 20-25 °C to obtain a light red solution,
concentrating and crystallizing the red solution to obtain a light red powder
product which is the lead-zinc mixing, floating and separating inhibitor.
Unless otherwise stated, the percentages stated in the invention are all
percentage by mass, based on 100% in total.
The invention has the advantages that:
It is generally difficult to inhibit pyrite and sphalerite in a mixed flotation
system by common inhibitors as ore surfaces are activated by copper ions and
are adsorbed with long-carbon-chain xanthate molecules. Congo red with
adsorption activity and sodium hydrosulfite with reducing property are adopted
to realize desorption of ore surface collectors, and zinc complex is used for
strengthening inhibition of sphalerite. Chemical adsorption, complexing effect
and electrochemical reduction are achieved, and combined inhibition effect on
sphalerite and pyrite for mixed flotation is achieved.
The technical scheme of the invention is further described below by way
of embodiments.
