When a player clicks on a rock they will hit it with their pickaxe and attempt to extract the ore The higher level the rock (e g adamantite and runite) the longer the mining procedure will take requiring the player to have some degree of patience After the ore has been mined the rock will no longer have a visible vein of colour for a while
Sometimes the gold is pounded directly into the caliche and needs to be removed with a pick or crevice tool Caliche layers which are close to the surface allow small-scale dry-washing operations to be economically feasible because of the lesser amount of gravel and material which needs to be shoveled off the gold deposits
This is also relevant to the effective closing of mines that have completed their life cycle Models for ore deposits that when mined have minimal impacts on the environment (such as deposits with no acid-generating capacity) and for deposits that may be available to innovative in-situ extraction will be important for the future
The other parameter that SGS experts consider when designing refractory gold treatments is whether or not to preconcentrate the gold-bearing ore This is usually done by flotation of arsenopyrite pyrite or other gold-bearing sulfides To be economically justifiable preconcentration should meet two objectives
