Rate testing a plant grab sample is often known as a hot float. For samples prepared in the metallurgical laboratory, all conditions of grinds, reagents, pH and % solids etc are chosen by the operator. Hot floats are normally performed as is unless the intention is to add additional reagents or change pulp density and pH.
