    Abstract
    Two offshore placer mining experiments (PLAMEX) were conducted using submersible pumps specially designed by Central Mechanical Engineering Research Institute (CMERI), Durgapur (India) at 8 m water depth in Kalbadevi Bay (PLAMEX-I), Ratnagiri, Maharashtra, and off Paradip (PLAMEX-II), Orissa, to determine the effects on sediment grain size and heavy mineral assemblages. The PLAMEX-I results for the sediments off Kalbadevi Bay showed no major effects on the average sand, silt and clay, grain size, and the heavy mineral percentages. The PLAMEX-II results for the sediments off Paradip showed mixed effects due to the dynamic environmental conditions
