ALFRED ARTHUR LOCKWOOD, OF LONDON, ENGLAND, ASSIGNOR TO MUREX MAGNETIC COMPANY, LIMITED, OF LONDON, ENGLAND.
MAGNETIC PREPARATION OF ORES.
No Drawing.
To all whom it may concern:
Be it known that I, ALFRED ARTHUR LOCKWOOD, a subject of the King of Great Britain, residing at Baltic House, 27 Leadenhall street, in the city of London, England, have invented a new and useful Improvement in the Magnetic Preparation of Ores, of which the following is a specification.
This invention relates to the magnetic preparation of ores. This is effected according to this invention by treating an ore with a magnetic substance, an oily liquid and a solution of a sulfid of an alkali metal especially potassium monosulfid and potassium hydrosulfid. I have further discovered that it is not necessary to subject the oily liquid to a preliminary treatment in order that a magnetic oxid shall be retained by the oily liquid when agitated with water, the best results being obtained when the ore, magnetic oxid and oily liquid are agitated together, a soluble metallic sulfid being subsequently added.
By this invention it is found that metallic oxids or carbonates can be successfully subjected to a magnetic preparation to the exclusion of the gangue.
In the following examples there will be described methods of coating carbonate ores with a mixture of oil and a magnetic oxid.
Example I: 100 lbs. of a lead ore containing carbonate, phosphate and chlorid of lead is crushed to pass a screen having 24 meshes to the linear inch. The crushed ore is suspended in 80 lbs. of water by agitation and a mixture composed of 4 lbs. of finely ground magnetite and 2 lbs. of Texas residuum oil added thereto. After agitation for about ten minutes there is added while still agitating a solution of 3 ounces of potassium sulfid in water; the carbonate particles will be found to be successfully coated and the pulp is now in a state to pass through a wet magnetic separator. In some cases it is advisable to first add to the untreated pulp either some oily concentrate from a previous operation or a magnetic mixture composed of magnetite and an easily saponifiable oil.
Example II: 100 lbs. of an ore composed Specification of Letters Patent.
Application filed April 14, 1911.
Patented June 27, 1911.
Serial No. 621,135.
partially of copper carbonate is crushed as in the preceding example and suspended in 80 lbs. of water by agitation. To this pulp is added a mixture composed of 4 lbs. of finely ground magnetite and 2 lbs. of an easily saponifiable oil. WVhen after agitation the metallic particles of the ore have become coated there is added 200 lbs. of the ore and 160 lbs. of water and also a mixture composed of 8 lbs. of finely ground magnetite and 4 lbs. of Texas residuum oil. After agitation for about ten minutes an aqueous solution of 4 ounces of potassium sulfid is added while still agitating. It will now be found that the copper carbonate particles have been successfully coated and that the pulp is now in a good condition to pass through a wet magnetic separator.
What I claim is 2- 1. In the magnetic preparation of an ore, the process which consists in treating the ore with a magnetic substance, an oily liquid, and a solution of a sulfid of an alkali metal and magnetically separating the mixture.
2. In the magnetic preparation of an ore, the process which consists in adding to the ore a magnetic substance and an oily liquid, agitating the whole, adding a soluble metallic sulfid and magnetically separating the mixture.
3. In the magnetic preparation of an ore, the process which consists in adding to the ore a magnetic substance and an oily liquid, agitating the whole, adding a sulfid of an alkali metal and magnetically separating the mixture.
4. In the magnetic preparation of an ore, the process which consists in treating the ore with a magnetic substance, an oily liquid, and a solution of potassium sulfid and magnetically separating the mixture.
5. In the magnetic preparation of an ore, the process which consists in adding to the ore a magnetic substance and an oily liquid, agitating the whole, adding potassium sulfid and magnetically separating the mixture.
