Abstract
The invention relates to an iron-rich less-tin ore flotation depressing agent and a preparation method of the iron-rich less-tin ore flotation depressing agent. The iron-rich less-tin ore flotation depressing agent is composed of 5-10 parts of sodium carbonate, 8-15 parts of sodium sulfate and 13-15 parts of triethylene tetramine. If the prepared floating depressing agent is applied to iron-rich less-tin ore separation work, iron and tin ore concentrate quality can be obviously improved, mutual containing of iron and tin is obviously relieved, and the iron and tin ore floatation recovery rate can be improved. The preparation method has the advantages of being environmentally friendly, easy and convenient to operate and suitable for complex iron-rich less-tin ore flotation and has good industrialization prospect.
Description
Technical field
The present invention relates to a kind of high-iron and low-tin ore deposit depressing agent and preparation method thereof, belong to ore dressing field.
Background technology
Along with social development, resource utilization increases day by day, and ore properties becomes increasingly complex, and technique of preparing difficulty is increasing.Complicated high-iron and low-tin mineral original ore property is changeable, and symbiosis is close, explanation mutually, and particularly iron and tin mineral character are closely similar, and usually with fine grain teeth cloth symbiosis, separating difficulty is very large.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of high-iron and low-tin ore deposit depressing agent and preparation method thereof, in the detached job of high-iron and low-tin ore deposit, add depressing agent prepared by the present invention and can significantly improve iron, tin concentrate quality, obviously reduce iron tin and contain mutually, improve the flotation recovery rate of iron tin mineral.The present invention has environmental protection, simple to operation, has good industrial prospect, is suitable for the ore dressing application of complicated high-iron and low-tin ore deposit.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of high-iron and low-tin ore deposit depressing agent, it is characterized in that, and by the raw material of following weight portion, formed:
5～10 parts, sodium carbonate, 8～15 parts, sodium sulphate, 13～15 parts of triethylene tetramines.
On the basis of technique scheme, the present invention can also do following improvement.
Further, described high-iron and low-tin ore deposit depressing agent is comprised of the raw material of following weight portion:
7 parts, sodium carbonate, 15 parts, sodium sulphate, 15 parts of triethylene tetramines.
Further, described high-iron and low-tin ore deposit depressing agent, is comprised of the raw material of following weight portion:
5 parts, sodium carbonate, 8 parts, sodium sulphate, 15 parts of triethylene tetramines.
Further, described high-iron and low-tin ore deposit depressing agent, is comprised of the raw material of following weight portion:
9 parts, sodium carbonate, 11 parts, sodium sulphate, 13 parts of triethylene tetramines.
The present invention also provides the preparation method of a kind of high-iron and low-tin ore deposit depressing agent, comprising:
Get 13～15 parts, 5～10 parts, sodium carbonate, 8～15 parts, sodium sulphate, triethylene tetramine and mix.
