Relief: High positive Habit/Form: Commonly found as slender prismatic to bladed crystals with a diamon-shaped cross section showing the amphibole cleavage at 56° and 124°. Also found as anhedral to strongly irregular grains, which in some cases may poikilitically enclose associated minerals. Large grains or fine fibrous masses of hornblende may mantle or replace pyroxene.

My personal 'poor man fancy microscopy' favorite is the $120 Celestron Micro360. It is a real microscope anyone can use for basic size-by-size mineralogy (if you know what minerals you are looking at).). The Celestron allows you picture or video (with voice recording) taking of what you are viewing.

Abstract Dissociation of gold particles is tested in disintegration of Gurbey deposit ore samples under multiple impact effects in crusher DKD-300. It is found that in disintegration of gold-bearing schistose quartz ore, dissociation of gold particles larger than 100 $$mu $$ m in size extractable by gravity reaches 47%. The test results are confirmed by the data of the …

Grind to Liberate Mineral Grains. Once this has been determined the amount that the ore will have to be ground must be evaluated. If you examine mineral bearing ore under a microscope you will notice that the barren rock is joined with the valuable mineral, to separate the two the rock must be ground until there isn''t very much host rock left attached to the mineral.
