Oven Type Laboratory Dryer For drying ores, concentrates, grains, or other pulps in the laboratory, the (Oven Type) Laboratory Dryer is a very efficient and inexpensive unit. The cabinet contains five heavy wire mesh shelves which allow the air to circulate freely. A substantial and accurately wound resistance element is located in base and shielded … Read more
Running a thickener properly isn’t as easy as it looks. True enough, a thickener doesn’t make a racket like a ball mill, or spew out froth like a flotation machine, or bounce up and down like a jig, but down inside that big tank there is a lot going on just the same. You, as … Read more
Settling Rate by Particle Size
In order to develop rational methods of measurement and laboratory testing, it becomes necessary to study the general phenomena of settling rates. Since it was desired to give the public the benefit of these methods at as early a date as possible, together with the knowledge of the general principles of slime settling necessary for a … Read more
Introduction to an EXAMPLE Fresh Water System Water is pumped from the fresh water well to the camp tank which provides pressure and storage capacity for the camp. The camp distribution system is located between the well and the camp tank, such that the pipe between the camp and the tank may have flow in … Read more
A Flocculant like the Dry polymer (Percol 156) is used throughout the process to flocculate fine particles and increase the solids settling, filtration and clarification rates. Flocculant is prepared and aged in the skid mounted automatic flocculant mixing system. A control panel for the system is mounted on the same skid. Refer to the equipment manufacturer’s … Read more
Details of good silver sulphide leaching and filtration circuit operation and instructions for sequencing and preparing for startup. The following items must be checked before the equipment in this EXAMPLE Argentite Leaching Circuit is started. The leach tank agitators should be running. Check that the Argentite filter feed pump, drum filter, repulper and tailings sampling pump … Read more
Producing a Silver Flotation concentrate from this EXAMPLE Argentite (cubic silver sulfide (Ag2S)) Flotation Circuit enters the first of four successive Argentite leach tanks. The purpose of this leach circuit is to dissolve the silver and gold recovered in the Flotation Circuit. A high strength solution of sodium cyanide, air, and lime are added to the … Read more
In Preparation for Startup, the following items must be checked before the equipment in the filtration circuit is started. Check that the filters, repulpers, filtrate pumps, vacuum pumps, flotation blower, and transfer pumps are ready to run. Check that the cooling water compressant system is functional. The selected cooling water filter must be clean, and reclaim water must … Read more
