Acid rock drainage (ARD) prediction is a very important issue in order to predict and prevent environmental pollution associated with mining activities. Nowadays, simple tests are widely applied and established in the mining and consulting business for ARD by: Acid mine drainage, acid and metalliferous drainage (AMD), or acid rock drainage (ARD) is the outflow of acidic water from metal mines or coal mines.. Acid rock drainage occurs naturally within some environments as part of the rock weathering process but is exacerbated by large-scale earth disturbances characteristic of mining and other large construction activities, usually within rocks.
The International Network for Acid Prevention (INAP) is an industry-led group created to help meet this challenge. INAP exists to fill the need for an international body which mobilizes acid drainage (ARD) information and experience. The network was founded in Since then INAP has become a proactive, global leader in this field.

INTRODUCTION The U.S. Environmental Protection Agency (EPA), the states, and the Federal Land Management Agencies all need better tools to manage acid mine drainage at mine sites. This report examines acid generation prediction methods as they apply to non-coal mining sites. The global acid rock drainage guide (GARD Guide) The International Network for Acid Prevention (INAP) has consolidated relevant information and produced a global acid rock drainage (ARD) guide (GARD Guide) that summarizes the best technical and management practices for industry and stakeholder use.
‘RELIABILITY OF ACID ROCK DRAINAGE TESTING Dr. MacG. Robertson, P. Eng. and Linda M. Broughton, P&g. Steffen, Robertson and Kirsten, Vancouver, B.C. () ABSTRACT Ir is the quality of drainage water from sulphitic rocks in the field rhut determines the actual or porential environmenral impact of acid rock drainage (ARD).
Acid rock drainage (ARD), also referred to as acid mine drainage (AMD), is the outflow of acidic water from mining operations including waste rock, tailings, and exposed surfaces in open pits and underground workings. ARD forms as a result of the dissolution of sulphides, mainly pyrite (FeS 2) and pyrrhotite (FeS).
In response to frequent requests for advice and the need to improve existing practices, MEM has produced a separate prediction document entitled "Draft Manual of Guidelines and Recommended Methods for the Prediction of Metal Leaching and Acid Rock Drainage at Minesites in British Columbia" (Prediction Manual) (Price, ).

Acid Rock Drainage as a concern and part of all metals and mining operations. ARD is often mislabelled AMD or Acid Mine Drainage too. ARD is often mislabelled AMD or Acid Mine Drainage too. So, to better understand AMD and ARD, let’s begin by defining some terms like pH -The standard measure of acidity.
Acid rock drainage (ARD) is the natural result of oxidizing or “rusting” of certain types of sulfur-bearing minerals in the presence of water, air and bacteria.
ARD is a very weak form of sulfuric acid. Sulfuric acid is used commercially to make. GARD Guide (Global Acid Rock Drainage Guide).

Acid-rock drainage is the water-quality hazard resulting from the oxidation of iron sulfide minerals (Nordstrom and Alpers, ). The pH of acid-rock drainage typically ranges from 2 to 4, but can range to values as high as 8 and as low as -5 (Plumlee and others, ; Nordstrom and Alpers, ).

Typically in Nova Scotia, ARD occurs when pyrite and other sulphide minerals are exposed to water and oxygen, and react in a chemical oxidation process that releases sulphuric acid and metal oxides into watercourses downstream.
