    "Eddy Current" Separation, Small Particle Size Limit

    Dear Tech., "The small particle limit for electromagnetic separation" The title says it all. I am trying to get someone with IEEE access to tell me what the bottom line is in their article 334180."The small particle limit for electromagnetic separation Fletcher, D. Gerber, R. Dept. of ..." If I...

    hydrocyclones

    Dear Mr. S., The hydrocyclone is vastly overated. Take the flow formulas from any chart for a fluted nozzle. The head loss is that adapted for a fluted nozzle resembling the inlet of the hydrocyclone. The curvature is a minor factor, ingnore it. Just use the estimate for a straight one...

    The small particle limit for electromagnetic separation

    Sorry, The title doesn't show "eddy current" separation. But that is the exact title of the article. Do you have access to document IEEE 334184? It describes why conductors smaller than 0.5 mm do not respond well to "eddy current" forces. What does that article say? Once again, this involves...

    hydrocyclones

    Dear Mr. "s", May I please have a star on my previous post? I'll look up something on the CWC for you. Sideliner

    SAG-D - Steam extraction requirements?

    Dear sprintcar, Looks like big doins you way. Centrifugal slurry pump manufacturers usually have example applications similar to your problem. Try several vendors and get a tech rep. to help you. If they suspect potential sales, you'll get lots of loving attention. CD's and the like. If not...

    hydrocyclones

    Well, Hydrocyclone performance has been described by empirical formulas and charts. The leading vendor has done well for itself by stressing anticipated customer conditions in making application reccommendations. BUT, there is a lot wanting in a hydrocyclone. The reason that it is a staple in...

    The small particle limit for electromagnetic separation

    Well, The title says it all. I am trying to get someone with IEEE access to tell me what the bottom line is in their article 334180."The small particle limit for electromagnetic separation Fletcher, D. Gerber, R. Dept. of ..." If I had access, I'd do it myself. The google exerpt suggested that...

    Need Help energy calculations.

    Dear Friends, You guys are great!Thanks to you and Eng-Tips! I'll do some "figurin," scratch both ends, and let you finally know what I am up to doing. Give me at least a month. Sideliner

    Need Help energy calculations.

    Dear Mr. j2bprometheus, Yes, I do want to calc. flame temp. for some situation. Ohhhhhhhh, I am like sooo way past the times. I'm screwing around with the system so that regular adiabatic tables just won't do. And, it isn't an isothermal calculation either. As a cetified fossil for all to see...

    Need Help energy calculations.

    NEED: FREE Energy (GIBBS)? or Specific Energy for gasoline in kcal/mole or energy/unit. Can you bright minds help me out please. Years ago in College we did a combustion calculation appx. like the following. The latent heat (heat contained at start of process) of reactants were combined...

    Gold Ore Processing CIL CIP CCD Gravity

    Dear Mr. Backfill, Ok, time to start a bruhaha. Is there any of you Geo's out there got the guts to set the gold industry straight? Although carlin trend host rocks (as I recall)are silicate and carbonate based (sedimentary? and some metamorphic?), the common black gold ores there contain sooty...

    Gold Ore Processing CIL CIP CCD Gravity

    Dear Mr. Backfill, I can say from experience, from time to time the geo's get ripped off for grade. Watch those fine gentlemen at the mill! They'll say "not so" with a straight face! Sideliner

    Gold Ore Processing CIL CIP CCD Gravity

    Since I'm stuck on the sidelines, could any of you bright minds share some of your problems and curiosites with me? For example, did you ever have your recovery drop to say, 50%, over one night? Or,are all the new process instrument toys (and software)covering all the bases?(Or,are there...
