Abstract: PURPOSE:To quickly meet the condition of excavation by a method in which the image of a stratum which appears on a lens made of a wear-resistant material having a small frictional coefficient, set on the tip a rod, is observed by a fiber scope. CONSTITUTION:When a rod 1 is penetrated into natural ground B from a cut- faced side A by means of the oil pressure of an excavator 5, the images of strata appear in sequence on a lens 3 on the tip of the rod 1 as the rod 1 is penetrated into the ground. Since the lens 3 is made of a wear-resistant material having a small frictional coefficient, the soil adhered to the lens 3 is separated from the surface of the lens 3 without causing any damage to the lens 3 and also without interrupting the observation of another stratum. The image of the stratum which appears on the lens 3 is sent out from the end face 2a of a fiber scope 2 to an observatory section 4 where the quality of soil can be soon judged. The conditions of excavation can thus be soon met.

Calcium zirconate and calcium silicate are selectively eluted and separated from the resultant slurry to concentrate Zr. The calcium zirconate is then brought into contact and dissolved in concentrated hydrochloric acid to recover a Zr leachate. Sulfuric acid is then added to the Zr leachate to form precipitates of insoluble Zr salts and recover the Zr. The slurry after separating the precipitates of the Zr salts and washing is neutralized with an alkali and recovered as zirconium hydroxide, which is then dried, fired and pulverized to produce the aimed ZrO2 powder.
