'fnp AtvrERrcAN MrxERALocrsr JOURNAL OF THE MINERALOGICAL SOCIETY OF AMERICA Vor,. 8 JUNE, 1923 No.5 MINERALOGRAPHY AS AN AID TO MILLING1 Brrrs TsousoN,University of Toronto The accurate determination of the opaque minerals present in an ore is very often of prime importance to the mill-man if he would work out the problem of separation intelligently. It is sufficiently obvious that a chemical analysis or an assay will only give him data as to the elements present and will leave him more or lessin the dark as to the minerals representedin the ore. Since it has been found that certain sulfidesare more amenable to flota- tion methods than others, the value of accurate mineralogical determination of the ores would appear to be particularly necessary 'in this form of milling. However, it should also be quite evident that any milling problem would be benefited at its inception by a careful study of the mineral content of the ore, the approximate quantitative proportions of the minerals present, and their mutual inter-relationships. As far as the writer is aware the only satisfactory method for examining these ores microscopically is by means of , polished sections in reflected light. This branch of Mineralogy, known variously as Mineralography or Mineragraphy, may also be applied to the microscopic study of mill-products in the difierent stages of separation. Where the fragmental ma-terial is fairly coarse a thin layer of it may be set in melted sealing-wax and polished in the ordinary way. If the material is fine enough to pass through a 4S-meshscreen, before polishing, it must be mixed with a combination of melted sealing-wax and balsam. -

Overview of the Nickel Market in Latin America and the Caribbean
INSG SECRETARIAT BRIEFING PAPER April 2021 – No.35 Overview of the Nickel market in Latin America and the Caribbean Ricardo Ferreira, Director of Market Research and Statistics Francisco Pinto, Manager of Statistical Analysis 1. Introduction At the suggestion of the Group’s Brazilian delegation, it was agreed by members that a report, based on INSG Insight No. 26, published in November 2015 entitled “An overview of the nickel industry in Latin America”, be prepared by the secretariat. This would include an update of the operations that resumed production (e.g. Falcondo in the Dominican Republic), and also discuss how the emerging battery market might influence nickel usage in the region as well as the possibility of nickel scrap usage. This detailed and comprehensive Insight report, the 35th in the series of INSG Insight briefing reports, provides members with the results of that research work. In Latin America and the Caribbean, the nickel producing countries are Brazil, Colombia, Cuba, Dominican Republic, Guatemala and Venezuela. The Dominican Republic stopped nickel mining and smelting in October 2013 but resumed production at the beginning of 2016. Venezuela has not produced since mid-2015. All of these countries mine nickel and process it further to produce intermediate or primary nickel – mainly ferronickel. Most of the mined ore is processed within each country, and then exported to overseas markets, but Brazil and Guatemala also export nickel ore. In terms of usage only Brazil and Mexico are relevant regarding the global nickel market. The first section of this report briefly describes existing nickel deposits in the region. -
Rebel Attacks on Nickel Ore Mines in the Surigao Del Norte Region
Mindanao, Philippines – rebel attacks on nickel ore mines in the Surigao del Norte region The attacks On 3 October 2011, three mining firms located in and around Claver town in the Surigao del Norte region of Mindanao, Philippines were attacked by the rebel group known as the New People’s Army (NPA). It was reported that the attacks were prompted by a refusal of the mining firms to pay a "revolutionary tax" demanded by the NPA. The affected mining firms are the Taganito Mining Corporation (TMC), Taganito HPAL Nickel Corporation and Platinum Group Metals Corporation (PGMC)1. According to news reports and Gard’s local correspondent in the Philippines, some 300 NPA rebels wearing police/military uniforms staged coordinated strikes on the three mining facilities. The rebels attacked TMC’s compound first, burning heavy equipment, service vehicles, barges and buildings. Other rebel groups simultaneously attacked the nearby PGCM and Taganito HPAL compounds. Unconfirmed reports indicate that, unfortunately, casualties were also experienced during the attacks. All foreign vessels anchored near Taganito at the time of the attacks left the anchorage safely. The current situation The Philippine Government has stated that the situation is now contained and has deployed additional troops in the area to improve security and pursue the NPA rebels. However, according to Gard’s local correspondent in the Philippines, threats of further attacks made by the NPA in a press release are believed by many to be real. According to the latest press releases (Reuters on 5 October), Nickel Asia Corporation has resumed operations at its biggest nickel mine TMC and expects to ship ore in the next three weeks. -

Myths of Deep and High Stress Mining — Reality Checks with Case Histories
Deep Mining 2017: Eighth International Conference on Deep and High Stress Mining – J Wesseloo (ed.) © 2017 Australian Centre for Geomechanics, Perth, ISBN 978-0-9924810-6-3 doi:10.36487/ACG_rep/1704_58_Suorineni Myths of deep and high stress mining — reality checks with case histories FT Suorineni University of New South Wales, Australia Abstract The theme of this conference is ‘deep and high stress mining’. Obviously, mining at depth and in high stress is a current challenge and will continue to be so. Despite the several years of dedication to this subject and its importance, the definition of what is ‘deep’ and ‘high stress’ remains a matter of conjecture. Clear understanding of these terms, are fundamental to the design of excavations to achieve the benefits of the knowledge accumulated on the subject over the years. This paper aims at critically examining conditions that constitute high stress and explores what is ‘depth’ in the mining context. International case histories are used to demonstrate how a misunderstanding of ‘depth’ and ‘high stress’ can result in wrong mine layouts and excavation designs. The paper then provides conditions that constitute high stress and deep mining as a guide to mine layouts and the design of excavations to cope with these conditions. Keywords: deep mining, high stress, case histories 1 Introduction Stress is a significant factor in determining the safe and economic extraction of orebodies and, hence, an important consideration in determining mining methods. Stacey and Wesseloo (1998) state that from the point of view of planning of mining operations, the in situ stress field is the most important input parameter for modelling of excavations. -
