    Artisanal and Small-Scale Gold Mining

    GUIDANCE DOCUMENT Developing a National Action Plan to Reduce, and Where Feasible, Eliminate Mercury Use in Artisanal and Small Scale Gold Mining Working Draft August 17, 2015 Foreword The Minamata Convention on Mercury, opened for signature in October 2013 in Japan, creates a blueprint for actions to protect human health and the environment from anthropogenic emissions and releases of mercury and mercury compounds. Article 7 of the Minamata Convention addresses the largest anthropogenic source of mercury pollution, artisanal and small scale gold mining (ASGM). Under Article 7, countries where mercury is used in ASGM are required to take steps to reduce and, where feasible, eliminate the use of mercury. Because the ASGM sector is closely tied to complex economic development and poverty issues, the Convention allows flexible, country-specific solutions through the development of an ASGM National Action Plan (NAP). Although each country’s NAP process will be unique, Annex C of the Minamata Convention provides a list of elements that must be included in each NAP. This document represents an expansion of the UNEP’s Guidance Document: Developing a National Strategic Plan to Reduce Mercury Use in Artisanal and Small Scale Gold Mining (UNEP 2011), and is intended to reflect Convention obligation and other advances in understanding of the ASGM sector. This document provides guidance to countries in formulating NAPs that are compliant with the requirements of the Minamata Convention, and provides technical, legal and policy information on issues related to ASGM, which can be useful when preparing and implementing the NAP. Although the use of this guidance is not a requirement under the Minamata Convention, this guidance is intended to assist countries with the preparation of their NAPs.

    90 DISCCSSIO-U ON SIZING OF CRUSHED NIBEEhLS. [Minutes Of Mr. Commans. Au!hor, when speaking of the digiculty of screening particles less than l& to 1 nlillimetre in diameter, was referring to screening in a wet condition, as commonly was the case with ore, and did not intend to referto thescreening or sieving of drymaterial, as Mr. J. H. Saunderson would seem to suppose. On the other hand, undoubtedly, even withdry material, a difficulty wasoften experienced with fine sieves of the meshes getting choked ; and if that was obviated in themachine referred to byMr. Saunderson, it was certainlya step in the right direction. With Mr. Garland's remarks about the jigger bottom having a forward inclination, he quite agreed. That plan should never be adopted, and whatever fall was required toassist the movement of the ore shouldbe obtained by slightly lowering each successive sieve, or the depth of the bedding, the sieves themselves remaining horizontal. Correspondence. JIr. Bartsch. Mr. W. J. BARTSCH,of Siegen,supplemented theAuthor's description by some details of results obtained with the Bartsch concentrator. As wouldbe seen from Figs. 45, that appliance consisted of a convex circular table carried at the centre on a bearing b, and at the circumference by rollers c. Radial blows were imparted by a cam f, and the slime and wash-water dis- tributors revolved over thetable, the main water-pipe being bent in a parabolic curve. The usual diameter of the table was 134 feet. For every 30 revolutions of the shaft, 120 bumps were imparted to the table, in which time(one minute) the distributors made half a revolution of the table.
