where r is the measured cumulative recovery of either valuable or gangue at time t, R is the calculated equilibrium recovery as t → ∞, and K is a first-order rate constant of mass removal (units of time −1) that describes the shape of the time–recovery curve at small flotation times.Thus, each time-recovery profile can be characterized by two parameters, R and K, which have statistical ...
Oct 02, 2013· @CharlieParker I could have used np.float instead, since it's just an alias of Python's builtin float.Python floats are 64-bit (C double) on almost all platforms.float and np.float64 therefore usually have equivalent precision, and for most purposes you can use them interchangeably. However they aren't identical - np.float64 is a numpy-specific type, and an np.float64 scalar has different ...

Float glass is a sheet of glass made by floating molten glass on a bed of molten metal, typically tin, although lead and other various low-melting-point alloys were used in the past. This method gives the sheet uniform thickness and very flat surfaces. Modern windows are made from float glass. Most float glass is soda-lime glass, although relatively minor quantities of specialty borosilicate ...
