leachable1944

1944 Exper. Station Rec. Apr. 450 Potassium could be changed biologically from a leachable to a nonleachable state.

1955 Sci. News Let. 27 Aug. 132/2 Experiments indicate that an average of only about 25% of the thorium and uranium in granite rock is ‘leachable’.

1972 Ann. Rep. Freshwater Biol. Assoc. XL. 40 This contrasts with dead leaves from which leachable substances are said to disappear in about a week.

1972 J. G. Cruickshank Soil Geogr. ii. 46 Maximum mobilisation of leachable substances is related to both the volume and composition of the organic leachate.

1973 Nature 13 Apr. 452/2 The concentrations reported include the contribution of acid leachable mercury associated with particulate material.

1960 tr. Wks. V. G. Khlopin Radium Inst. (U.S. Atomic Energy Comm.) VI. 123 It was established by experiments set up to study the leachability of radioelements from minerals that the isotopes of thorium (Th, RdTh) and radium (ThX) behave differently.

1962 Geochim. et Cosmochim. Acta 26 1137 In an effort to determine the possible sites of thorium and uranium in the samples, a study of their leachability in hot 2N hydrochloric acid was undertaken.

1983 Current Affairs Bull. Dec. 30/1 The significant geochemical advantage of Synroc over the major alternative, glass, is its lower leachability rate under realistic geological conditions.

1994 Northern Miner 3 Oct. 2/4 Gold mineralization is fine-grained (less than 150 mesh), and bottle-roll cyanide leachability analyses returned recoveries of more than 90% within two to six hours.
